The base of the pyramid was around seventy-five meters on each side and it would have been around one hundred and five meters when completed. Like other Middle Kingdom pyramids the body of the pyramid was constructed from mudbrick and clay (rather than durable stone) clad in limestone. The mudbrick core was built in stepped form perhaps to try, in vain, to give the monument greater stability.
Unlike earlier twelfth dynasty pyramids the substructure of the pyramid is a complex network of interconnected passageways and was clearly built as a burial site for the wives of the pharaoh, as well as the king himself. It is suggested that the complexity was an attempt to fool tomb robbers but it may also have had a ritual significance, as the chambers were sometimes described as the home of Osiris.

as its fascinating there's a whole complex of 0:27 · rooms Way Beyond the simple needs of disposing of a dead body this is not 0:32 · something you find in other pyramids the pyramid is off limits to the public 0:38 · weakened by serious structural problems it could be dangerous for visitors but a few daring archaeologists 0:45 · have risked venturing inside all the same with our cameras given special permission to accompany them look at the 0:51 · crack in this chamber it still looks like it could collapse at any moment even for experts this little 0:58 · known pyramid remains a real puzzle together we'll try to find some Clues to help us decipher this Millennia old 1:05 · edifice my God there's still bones in there to shed light on all these 1:11 · Mysteries our scientists were granted permission to venture inside Egypt's most iconic pyramids with a latest 1:17 · generation laser scanner it's quite tight in here what happened during its construction for this Monument to have 1:23 · ended up in such a state what did this dilapidated pyramid originally look like and why did the ancient Egyptians build 1:30 · such an extensive network of passageways now seen for the first time using 3D 1:36 · models we will show you everything invisible to the naked eye with a few clicks we can do 1:42 · measurements that would be very complicated to carry out in situ this Ultra detailed digital 1:47 · modeling should provide our experts with new answers in this ongoing scientific investigation which began 200 years ago 2:01 · [Music] 2:30 · deep in the Sands of Egypt is an exceptional site little known by the public the daser 2:37 · plateau it's around 30 km from 2:43 · Cairo this is where the first two giant pyramids of History were built the Red 2:48 · Pyramid and the bent pyramid but in the distance Behind These 2:54 · two giants you can make out a strangely shaped Steep Hill this in fact is is 3:00 · also a pyramid one of the last built by the Pharaohs about 3,800 years 3:06 · ago villagers living around here gave it its somewhat disturbing name the Black 3:11 · Pyramid it doesn't look very much like a pyramid at all although it's called The Black Pyramid it just looks like a black 3:18 · rugged hill with a kind of tower sticking out of the top at first sight there's nothing to 3:24 · suggest that under this dilapidated construction there's an extensive maze of passageways probably the most 3:30 · sophisticated Network ever built under an Egyptian 3:40 · pyramid Frank Monier has been fascinated by the pyramids of Egypt since 3:45 · childhood an engineer by profession he studied the construction of these monuments in great detail in the process 3:51 · becoming one of the world's leading authorities fascinated by the Black 3:57 · Pyramid he can draw a plan of its Apartments almost from 4:03 · memory here I've sketched A View from Above of the Black Pyramid at desure A 4:08 · View from Above the base of the pyramid with its funeral Apartments here we have the whole extent of the funeral Network there's nothing 4:15 · like the complexity of these funeral Apartments anywhere else so what would be really interesting to scan would be 4:21 · in priority the part dedicated to the queens and the part dedicated to the king to get a clear review of everything 4:28 · that went on inside these apartment scanning the innards of this pyramid 4:34 · could well be the way to better understand this mysterious edifice because there is still little 4:41 · known about its interior the construction is off limits to the public and is rarely visited even by 4:47 · egyptologists for this unprecedented Mission Frank Monier has called on archaeologist albor BR 4:53 · bampu an expert in digital imaging he'll be able to make a complete three-dimensional and extreme detailed 5:00 · model of these apartments it's a pyramid that's not yet 5:06 · been opened up to the public I'll be discovering it myself and I have no idea what the conditions will be in terms of 5:12 · the humidity and heat I feel privileged to be allowed into this Monument because very few people have been here and 5:17 · that's pretty exciting entering the Black Pyramid is a 5:23 · rare opportunity and whenever anyone does the 5:29 · entrance has to be totally cleared because just like in the time of the Pharaohs it is sealed off with blocks of 5:34 · stone to protect it and keep out Intruders Albom re is going to be using 5:41 · a very high performance piece of technology a lar digital scanner one of the most miniaturized that 5:49 · exists it weighs only 800 G but the insides of pyramids are usually very 5:55 · tight spaces in which it's difficult to move around so it could still be a difficult task here I'm configuring it 6:02 · so that the scanner and my phone are communicating that means I'll be able to get some feedback of what the scanner is 6:11 · see we were exceptionally granted authorization to accompany Al on this groundbreaking 6:22 · Mission it is the first time a piece of modern technology will be used inside this pyramid 6:30 · the lar scanner makes a noise as it starts digitizing the 6:37 · space after a few meters albon Bri checks that the device is working 6:43 · correctly here we can see this little Green Dot that's where the scanner is and it scanned this wall here this one 6:50 · so yes it's all in [Music] position the laser scanner can record 6:57 · hundreds of thousands of points every second in every direction it can thus measure a space 7:03 · with absolute Precision to the millimeter a totally unparalleled feat of 7:12 · Technology it's a real Labyrinth once you're in here the idea is to get a precise scan of all these 7:17 · structures with which we'll be able to document in a very detailed way the general dimensions of the spaces I'm 7:25 · surveying on a map given to him by Frank Monier Alon Bri identifies the various 7:30 · spaces to be digitized as a priority so we came down the sloping 7:36 · tunnel and through a first passageway a first Corridor which was reinforced by some more modern masonry now we're 7:43 · coming to a fork and we'll head towards the area that was dedicated to the 7:51 · king but time is limited the conditions are stifling with 7:56 · the air inside the pyramid barely circulating or being refreshed you cannot stay for long in this 8:02 · Subterranean domain the humidity is very high and pretty oppressive yes it's 8:08 · quite tiring on his way down the tunnels Alon 8:14 · Bri scans several empty 8:24 · rooms we've made progress and we've got the rough outline of a plan I've looked 8:29 · into all the little rooms on either side of the central Corridor and now we're about to go into the anti chamber and 8:34 · then the king's [Music] chamber the king's burial chamber the 8:41 · spiritual heart of the pyramid albon Bri Marvels at the pharaoh's sarcophagus carved out of a 8:48 · single piece of pink Granite from Aswan one of the most solid rocks found in Egypt despite it being almost 4,000 8:56 · years old its state of conservation is impressive 9:02 · in contrast the dilapidated state of much of the walls is quite 9:09 · surprising scanning gives us an overall view of the condition of all these structures all the traces you see on the 9:15 · vaulted ceiling on the masonry joints you can see how it's crumbling there even cracks it's clear that there's 9:21 · enormous pressure bearing down structurally on the vaulted 9:26 · ceiling the pyramid clearly had a few construction issues 9:31 · the results of the scan should help us find out more but the pharaoh's Builders must 9:36 · have made mistakes in the very design of the structure for the pyramid to show such signs of dilapidation 9:44 · now to get a better understanding we have to consider the period in which it was built the Middle 9:50 · [Music] Kingdom it was faroh amenemhat I theii who had this strange Pyramid built 9:56 · almost 4,000 years ago he reigned in around 1800 bcee and is 10:02 · considered the most powerful Pharaoh in one of the most prestigious lineages of ancient Egypt the 12th 10:09 · Dynasty the 12th dynasty of ancient Egypt is part of a period the 10:15 · egyptologists called the Middle Kingdom a kind of classical Age amonth III was the last great king of the 12th Dynasty 10:23 · he ruled for 46 years and he inherited a prosperous country that was was 10:29 · administratively functioning very well and he was in an ideal position to do Innovative architectures and to develop 10:37 · and expand a building program before the Middle Kingdom Egypt 10:44 · had been through a period of instability and division lasting several centuries during which no pyramids were 10:51 · built but during the 12th Dynasty unity in the country was restored and the 10:56 · Pharaohs wanted to reconnect with the architectural Prestige of their glorious ancestors there is a centralized State 11:03 · there is one strong pharaoh and the building of pyramids comes back into 11:09 · fashion on the same level of importance perhaps as it had been in the Old 11:14 · Kingdom the country's most famous pyramids those on the Giza Plateau were built in the period we call the Old 11:20 · Kingdom almost 800 years before the reign of ammat 11:26 · theii these Kings of the 12th Dynasty considered themselves the direct Heirs of the kings of the Old Kingdom thus 11:33 · predicating their legitimacy on the architectural and historic Legacy they copied to some extent The Monuments of 11:39 · the kings of the Old Kingdom it is hard to believe now but 11:44 · when it was finished the Black Pyramid looked like a classic pyramid of the Old Kingdom the Pyramid of kufu for 11:56 · example could it still be possible to find traces of the black pyramid's past 12:01 · Splendor What secrets are concealed under this shapeless Hill on the outside today the Black 12:09 · Pyramid doesn't look very exciting but inside there's a whole complex of rooms 12:15 · Way Beyond the simple needs of disposing of a dead body after a few weeks of digital 12:22 · analysis the results of the scan are finally ready the egyptologist Mark leoner was 12:28 · impatient to see see them it's the first time he's ever seen the internal network of the pyramid with such a level of 12:35 · precision laser scanning captures every detail of the reality it almost looks 12:41 · like the real thing like you're in there you can pan in you can pan out and 12:49 · you can twirl it above all this tool lets the archaeologists save precious time to map 12:57 · something complicated like this will take weeks months you go through with a laser scan and it takes tens of 13:03 · thousands of points per second every point is the equivalent of an archaeologist bending down stretching a 13:10 · tape measure and then drawing it on tracing paper on a drawing 13:17 · board Mark is an authority on the Pyramids of Giza and therefore used to The Fairly minimalist Interiors of the 13:23 · pyramids of the Old Kingdom the first thing to strike him about this 3D model is the huge extent 13:30 · of the underground Network it's a complicated internal 13:35 · structure in fact it's considered to be the most elaborate underground structure of any 13:41 · pyramid with the most Chambers and passageways thousands of kilometers away 13:48 · in Paris Frank Monier is able thanks to the lar scanner to evaluate the unusual 13:53 · dimensions of the passageways the operation only takes a few clicks and gives a result of the utmost 14:00 · Precision using this tool I can measure the expanse of the apartments that are under the 14:06 · pyramid here we have the view from above and we can carry out a few measurements to give us an idea of the 14:12 · dimensions of this network for example for this first Corridor here we already have a length 14:18 · of 42 M let's measure the corridor of the king's apartments from the two ends 14:24 · going from one room to the other over 46 M so you can see that if we add up all 14:30 · the data we end up with over 400 m of passageways that really is a lot and in 14:35 · all about 20 or so rooms yes all the other kings buried 14:42 · themselves in a pyramid with one maybe two ascending passages and a few 14:48 · Chambers in the Black Pyramid there are tens and tens of rooms and Corridor is 14:53 · connecting all of these rooms this is not something you find in other pyramids 15:00 · but what was the point of this huge underground Labyrinth our investigation with the lar scanner may help us 15:06 · understand it somewhat better in any case the sophistication of this network is in sharp contrast to the dilapidated 15:13 · state of the outside of the structure for each time you look at it the same question comes to mind how did this 15:19 · pyramid end up looking like this the egyptologist Meredith brand has 15:27 · come looking for answers in situ she's discovering the site for the first 15:33 · time and immediately spots some initial Clues when I walk up to it I don't even 15:40 · see a pyramid at first from the distance it almost looks like a mountain or some kind of natural geological feature like 15:47 · a giant thing of sand almost but up close it's clear that's not the case at all it's really solid mud brick and each 15:55 · of those mud bricks I can see the individual ones all throughout this slope on the 16:02 · Top This Strange Hill is in fact a mountain of carefully stacked bricks in the middle of the 16:10 · desert all the same size the bricks were made of a mixture of sand and clay 16:15 · extracted from Nile mud reinforced with pieces of 16:20 · straw at the summit part of this brick work is still in place but on the lower slopes it's all 16:27 · just pieces wow there's so many mud bricks that have 16:34 · fallen from this pyramid all the way down the slope so what looks like sand is 16:40 · actually dirt and debris of broken down mud brick these bricks are still in a 16:45 · rectangular shape and we can still see there's remains of some of the dried out straw that was used inside of them to 16:53 · make them strong and there's even some finger Impressions from ancient Builders the 16:58 · these mud bricks are proof of just how talented the Egyptian Architects and Builders were they knew what they were 17:05 · doing they were able to make mud bricks like this that would last for thousands and thousands of 17:12 · years the use of these clay bricks was in fact an innovation in pyramid 17:17 · [Music] construction the pyramids of the Old Kingdom were made entirely of stone and 17:24 · everlasting material but which required considerable means to mine transport and 17:31 · [Music] assemble several centuries later then the pharaoh's Architects opted for more 17:37 · modern methods in the Middle Kingdom King started to think about the economy how 17:43 · they build structures and they decided that it's too much of an ordeal to make an entire pyramid out of stone so 17:50 · instead they had the genius idea of having the center being made out of mud brick it was cheaper this was an 17:56 · intelligent moneysaving Endeavor that the advantage of mud bricks was that they could be made anywhere in Egypt 18:03 · they could produce the bricks and then transport them by boat to the work site so the use of mud bricks rather than 18:08 · Stone was more to do with Logistics than technique millions of mud bricks were 18:15 · methodically laid by the pharaoh's workers to construct the core of his 18:21 · pyramid it's estimated that 20 million bricks were required to make the whole pyramid complex 18:29 · but the ancient Egyptians still wanted their Monument to look like a proper 18:35 · pyramid once the brick core was finished the whole structure was totally covered with a facing made of a unique stone 18:42 · Limestone from Tura this stone is so pure and white 18:49 · that it can be considered a sort of Egyptian marble originally all Egyptian pyramids were covered in 18:56 · it thanks to these ingenious construction techniques the Egyptians were able to construct an absolute giant 19:04 · here in fact the Black Pyramid had a base that measured 105 M by 105 M and 19:10 · was 75 M high it was the largest pyramid of its era 75 M that's equivalent to a 25-story 19:20 · building am menim hat the thirds pyramid became the sixth largest pyramid ever built in Egypt out of the hundred or so 19:27 · in total 19:33 · the only trouble was the Pharaoh and his Builders had made a big mistake they had 19:38 · underestimated the destructive actions of stone 19:43 · thieves these blocks have been looted to reuse the stones in or heavy blocks uh 19:49 · in other building project to make use of their power and the history behind these blocks because these Stones had a cultic 19:57 · and religious drop the Limestone was stripped away it was all Stripped Away 20:02 · and reused elare which left the internal structure the brick work structure naked 20:08 · and over the Millennia with rain and wind erosion the bricks got turned into 20:14 · Rubble but just like the stone the bricks too were objects of 20:19 · desire another Factor contributing to the destruction of the pyramid was that people took bricks from the structure to 20:25 · use as a natural fertilizer on their fields the pyramid in its present dilapidated 20:35 · State Mark Leonard tries to imagine what the pyramid looked like almost 4,000 years 20:42 · ago at the foot of the edifice there's a strange cluster of white 20:49 · rocks did these blocks somehow miraculously escape the stone 20:55 · thieves now this is amazing we can actually see here one of the casing 21:02 · stones and it could even be a Cornerstone this is really nice and 21:08 · smooth brilliantly white this whole galaxy of casing stones 21:15 · that we see here once covered the entire pyramid just like snu 800 years earlier 21:22 · covered the entirety of his bent pyramid with the same fine quality White tour limestone 21:30 · the bent pyramid barely a kilometer and a half distant is the only one in Egypt 21:35 · to have retained most of its casing of Tura Limestone while the ravages of the 21:41 · Millennia have given the pyramid this somewhat beige look it would have originally been a dazzling white when 21:47 · you look at the Ben pyramid of snafu it gives you an idea of what this dark black Tower once looked like it was a 21:54 · gleaming white geometric shape it must have been like the sun shining a newly fallen snow it must have been truly 22:03 · blinding covered in its facing the pyramid must have looked like a perfect triangular prism of white stone 22:10 · reflecting the light of raw the sun god this is an amazing testimony that 22:16 · tells us what the pyramid once was when we are confronted by this big black ruin 22:22 · it's pieces like this that archaeologists have to put together to understand the ancient path 22:33 · Mark Leonard wants to compare the inside to what he saw on the lar Digital 22:38 · model there are no tourists at the site the place is totally 22:44 · deserted in the almost 50 years of his archaeological career Mark has been inside this pyramid only once 22:53 · before I'm very excited to go in this pyramid because it's not open to the public I work at the Pyramids of Giza 22:59 · and the Great Sphinx thousands of tourists every day all around us but here it's way off the Beaten 23:12 · Track once inside Mark is immediately struck by the quality of the work done by the pharaoh's 23:23 · Builders I have to Marvel at the beauty of this place the work the work is just 23:30 · Exquisite beautiful white tour Limestone vating the joins are stupendous true 23:37 · finesse in masonry the walls of the tunnels dug 23:43 · underground were lined by slabs of Tura Limestone Egypt's most refined Stone the 23:48 · same that was used to cover the 23:53 · outside the beauty of this stonework is all the more amazing when you think think that it was never meant to be seen 24:01 · it was all for the king in the afterlife it was in this Maze of pure 24:07 · Limestone that the Pharaoh could enjoy his eternal rest ah the corridor to the 24:17 · King on the Pharaoh sarcophagus Mark immediately spots quite a striking 24:24 · symbol how nicely done these eyes are when the king mummy was put inside 24:30 · symbolically these two eyes at the far north end of the East Side allowed him 24:35 · to look out to the Rising Sun this representation is quite typical 24:42 · of the funeral customs of the Middle Kingdom on the coffins in sarcophaga of that period they always represented 24:49 · looking East a pair of eyes which gave the deceased lying down inside a sort of port hole through which to see the 24:55 · outside and in particular to see the Rising Sun which was the driving force of Egyptian 25:03 · religion but for Mark something in the room does not make sense I don't know the exact 25:09 · measurements I don't have my tape measure with me but it looks too wide to come in that 25:16 · doorway the sarcophagus does indeed look too wide to have been brought through the 25:23 · corridors on the 3D model created by means of the lar scanner we can now measure the Dimensions 25:29 · exactly and the measurements confirm Mark's impression with its base the sarcophagus 25:35 · is 2.6 M long and 1.15 M wide but the corridor which leads to the king's 25:41 · chamber is never any wider than 1 M so how did the ancient Egyptians get the sarcophagus to this place in the 25:49 · pyramid there are grounds for thinking that the sarcophagus was placed there before the pyramid had been 25:56 · constructed so they first of all dug they dug pits and trenches and turn these into the underground 26:04 · Apartments most of the network of the black pyramid's passages was dug as tunnels in the clay soil of the Dasher 26:14 · Plateau but for certain rooms they must have dug pits from the surface into which they could lower the most 26:20 · voluminous items such as the huge 26:25 · sarcophagus a very impressive feat when when you consider the weight of this 26:31 · monolith the sarcophagus is pink Granite it's a very hard rock very heavy it 26:37 · alone weighs between four or 5 tons equivalent to four large 26:45 · cars once the chamber was finished and the vaed ceiling in place the pit was filled up with brick 26:52 · [Music] work studying this impressive 26:58 · sarcophagus Mark leoner has spotted another symbol familiar to 27:04 · him the truly remarkable thing is that the bottom is carved with these Gates 27:10 · which is a series of Palace Gates carved with bastions and niches which imitate 27:18 · the surrounding wall of the famous joser complex the step pyramid complex they're 27:23 · paying honor to the first pyramid Builder 27:30 · there certainly is a striking resemblance to this wall built 900 years earlier by a legendary Pharaoh joser 27:37 · founder of the Old Kingdom a model of prosperity unity and stability for all of ancient 27:45 · Egypt this is the best conserved section of the huge niched enclosure wall which 27:51 · surrounded his stepped pyramid in Sakara the first pyramid in human history 28:00 · so the presence of this motive on the sarcophagus did not come about by chance it's not just a nod and a wink it 28:07 · shows a true desire to Anchor their roots in the history of the first Egyptian dynasties it's above all a way 28:12 · of linking a men the third a pharaoh from the end of the Middle Kingdom to the first Sovereign of the Old Kingdom 28:19 · almost a thousand years earlier showing that there was a direct line from that legendary King to Amad the thir 28:28 · by depicting this Monument amenemhat III was confirming his link to the Glorious past of the Old Kingdom and its gigantic 28:40 · pyramids and yet some of the layout is decidedly at odds with what we usually see in classic 28:49 · pyramids at the entrance to the King's network Mark lonard notices a very narrow 28:56 · Corridor the way under the the southwest corner of the pyramid is a very very narrow 29:02 · Corridor and very difficult going everything is difficult because it's so humid down 29:09 · here I'm literally dripping with 29:15 · sweat the passage is particularly long and extremely hard goinging because of its 29:22 · narrowness with the data collected by Alon using the laser scanner a few weeks earlier we can measure just how narrow 29:29 · it is only 60 cm at the end mark discovers a 29:36 · surprisingly small room it too containing a 29:41 · sarcophagus although cluttered with stones it is strangely similar to the pharaoh's burial 29:50 · chamber a bit further along the corridor is another room identical to the first 29:59 · here inside the chamber itself her burio chamber you see also a beautiful Granite 30:07 · sarcophagus carved in the same style with the same decoration as the granite 30:13 · sarcophagus of the king inside it an unbelievable surprise 30:19 · awaits him my God there's still bones in there 30:27 · and even broken pieces of 30:35 · wood have these been in there from the beginning I don't know at the moment but 30:42 · it is truly amazing getting to film these bones is 30:48 · absolutely extraordinary but what are they doing here and to whom did they 30:55 · belong the archaeologists who discovered the bone in the 1980s had them analyzed 31:00 · and then replaced them in the sarcophagus and the tests revealed something quite 31:06 · amazing under the pyramid were the remains of two women there are two queens that are 31:14 · buried in this structure one we know her name is OD the second is unknown we know 31:20 · that one was around 35 when she died the other was was around 25 so they died 31:25 · relatively Young finding human remains in a pyramid is already a very rare 31:32 · occurrence but it's only the second time in history that women's Bones have been 31:37 · found usually in a pyramid complex there's an enclosure wall with a pyramid 31:43 · and then satellite pyramids on the side for important Royal women but Amin have the third changed all that we can see it 31:50 · perfectly clearly on the light our image two burial Chambers were built in the western quarters under the pyramid the 31:57 · these were for the tombs of two of amenemhat III's wives before this they took care to keep 32:04 · the Queen's Apartments totally separated but here there's no pyramid for the queen there are just Apartments 32:09 · underneath the one pyramid but why this Innovation why did 32:16 · the Pharaoh want to be near his Queens we don't know why he did this but 32:21 · one possible reason is that he wanted them to be closer to him in the afterlife the women are no doubt Al 32:28 · there to fulfill a protective function for the dead Pharaoh it's quite likely that a feminine figure would play a role 32:35 · in the Renaissance or resurrection of the king in his funeral complex it may 32:40 · have been some kind of particular regard for these two um women but all we can do 32:46 · is speculate we'll probably never know why 32:52 · Amad theii made this choice 32:59 · but it seems that some unexpected incident came to disturb the Eternal rest of his 33:05 · wives we return to Mark lonard underground what has particularly struck 33:11 · him about the innards of the Black Pyramid is the high number of cracks he can see pretty much all 33:17 · over everything shows cracking that's a crack that runs down the entire length 33:22 · of this Corridor and you can see the CRA de are becoming more and 33:28 · more numerous and even even here in the floor it's not only the walls and the 33:36 · lentils it's even the floor itself was was 33:42 · cracking you can imagine as they're dressing this down doing the final finish work you can still see their 33:47 · chisel marks all of a sudden it must have been a booming 33:53 · frightening sound that echoed through all the chambers and passages causing the workers to put down their tools did 34:00 · they run right away we can 34:06 · imagine the archaeologists have found indications that these cracks happened while the pyramid was being 34:13 · built the fact that this damage this subsidence this settling happened during the construction is proved by the 34:19 · patching up it was done by the ancient egyptions themselves in a lot of corridors and Chambers there are wooden 34:25 · beams which they place there to show up up where there had been a crack and there might be a 34:31 · collapse we have modern cross beams to to hold up everything but they are 34:39 · supporting ancient Cedar beams that amm hits people put to hold up whatever is 34:46 · above these beams are as old as the pyramid itself and that means they're 34:51 · 3,800 years old and there they are but what happened here 34:59 · why does the structure show so many signs of damage for part of the answer we have to 35:06 · go back above ground the Pharaoh May well have picked 35:13 · a poor spot for his pyramid despite having given it long and careful 35:19 · thought Dasher is 20 km south of the Giza Plateau the site on the outskirts 35:24 · of Cairo of the famous Great Pyramid of kufu dasu was a very famous place and uh 35:31 · especially to reconnect with ancestors when amam thei started to build his pyramid there were already pre-existing 35:38 · structures all over dashu such as the big pyramids of 35:43 · snfu snefru was one of the most powerful pharaohs of the Old Kingdom a ruler who 35:49 · achieved legendary status for ancient Egyptians who went so far as to deify 35:55 · him sfer was still V generated in the Middle Kingdom so 12th Dynasty Kings 36:00 · they went to dashur to build their pyramids and in many ways they were aligning themselves with the power of 36:07 · this pharoh from a long gone era it was at dashur that snfu had 36:13 · histories first giant pyramids built the Red Pyramid and the bent 36:20 · pyramid they were constructed in around 2,600 BCE eight centuries before the 36:26 · Black Pyramid but what surprises Meredith brand is the 36:32 · unusual location of a menam hat III's pyramid in relation to sniff 36:37 · Rus standing where I am at the amim the third pyramid it's clear that over there 36:42 · in dashore the ground is higher and we're here in a depression right here we 36:48 · are incredibly low the lar scanner should provide us 36:55 · with more information about exactly how deep the funeral apartments 37:00 · are to this end albon Bri pampo has to walk all the way around the structure to 37:06 · get readings of the level of the surrounding ground to compare to those of the pyramid's underground 37:12 · [Music] Labyrinth using the data collected by the scanner the 3D model gives us a 37:18 · perfect cross-section view of the monument and its various levels the color coding used here gives us 37:24 · information about the respective levels of the parts scanned the higher up you go the warmer the 37:30 · color getting redder and likewise the deeper you go the colder the color 37:35 · turning blue or Violet so we can see perfectly well on this side view that the whole complexity 37:42 · of the apartments is deep under the pyramid and is not inside the 37:49 · pyramid using the 3D liar model Frank Monier can now with just a few clicks 37:54 · establish the depth of the funeral Apartments underneath the Black 38:01 · Pyramid so let's measure how deep these apartments go I'll pick a low point at 38:06 · random here in this chamber for example and then pick a second Point by 38:12 · the entrance there that gives us a depth of 12 to 13 M so the complex of Apartments 38:19 · was dug down to a depth of 12 to 13 m a depth of 12 M that's equivalent to 38:27 · fourth [Music] basement at this depth Mark lener 38:33 · notices an opening in the ceiling which reveals something very strange about the Earth through which these tunnels were 38:41 · dug oh this is a good view of the Bedrock clearly it's gray Shale clay 38:49 · rust colored iron deposits but it's full of crack it's actually crackled it's not 38:55 · at all stable this Bedrock is the source of a lot of 39:01 · their problems to remain stable a pyramid 39:06 · should be built on Solid Rock not on Clay Frable 39:14 · ground it's a surprising mistake for Amat III's Architects to have made 39:19 · especially when you realize that the site they chose for the structure seems particularly poorly located in the 39:25 · topography people often assume that pyramids are in the middle of the desert but in fact if 39:32 · you visit Egypt you will see that the pyramids are on the edge of this great 39:38 · desert escarment and they are actually quite close to the 39:44 · cultivation but here even the experts are surprised by just how unusually close the Black Pyramid is to the Nile 39:54 · Valley the Pyramid of &m the thiri is Incredibly Close to the N Valley it's just right over there The Greenery the 40:02 · agriculture the civilization the cities the towns it's just a Stones throw away 40:09 · the ancient landscape in dasu was quite different from today's landscape the Nile shifted through the thousands of 40:15 · years and moved its bad sideways and um we have scientific evidence that the 40:21 · cultivated area and the the cultivation was much closer than it is today 40:28 · for egyptologists this decision to build the Black Pyramid so close to the Nile was a total engineering 40:35 · blunder the desert is dry the sand is far away from the water table and it's a 40:41 · great environment to build the Nile Valley on the other hand is water logged and the water table is also really high 40:49 · so by choosing to construct a pyramid at this site so close to the Nile Valley means that amim at the third's pyramid 40:55 · didn't really stand a chance it wasn't built on a solid foundation to last the clay soil under the Black 41:03 · Pyramid is porous so it's infiltrated by any rise in the level of the extremely close groundwater 41:10 · table water infiltration weakened the ground on which the pyramid was built then this weakened permeable 41:18 · ground must have undergone localized and irregular subsidence which was the cause of all 41:24 · the cracks you can see in the apartments apart as the pyramid Rose its weight 41:31 · bore down more and more heavily on its clay unstable and water loged base the edifice started to sink into 41:38 · the ground but there could be another reason for these structural 41:48 · problems the 3D model obtained with the lar scanner has shown us that the network of passages under the pyramid is 41:55 · much more extensive than what is usually found in pyramids what if am menum had the third 42:02 · by being too ambitious unwittingly undermined his own monument that simply doesn't work inside 42:08 · of a pyramid structurally one cannot have so many chambers and keep a strong 42:13 · Foundation to maintain a huge pyramid too many rooms too many corridors to consolidate perhaps they quite simply 42:20 · underestimated the reinforcing measures that would be needed and this led to structural 42:25 · problems they hadn't anticipated partip there's a lack of additional support 42:30 · from Limestone retaining walls which means the weight of all that mud brick is not being distributed and it's 42:37 · causing those internal facing Limestone blocks to 42:43 · crack at a certain point the weight of the structure exceeded what the vaults could support the pyramid subsided 42:50 · pressing down on the rooms and corridors underground causing cracks to appear everywhere 42:57 · but why did ammat III take this risk of weakening his tomb it's a bit of a mystery because we 43:04 · haven't found the contents of all these rooms and don't really know what their purpose was we don't actually know how 43:09 · the the different chambers were used but there are studies indicating that chamber systems are an image of the 43:16 · imagination of the Nether world and of the religious belief 43:22 · system the Nether world this is where the dead must face Osiris The God Who 43:27 · will resurrect them the Black Pyramid has its own roote which is in fact a representation of the 43:34 · complex root that the dead have to take in order to reach Paradise perhaps these rooms are in fact sorts of fictional 43:40 · regions of the Nether world the pyramid itself is a 3D representation of the Nether 43:46 · world this could be the great Paradox of the Black Pyramid in trying to create the best 43:52 · possible imitation of the Nether world in order to guarantee his access to Res Direction ammat thei in fact doomed his 44:00 · tomb to crumbling [Music] 44:08 · ruin there's one place under the pyramid where it seems only a miracle could have prevented a total 44:16 · collapse an incredible place so hard to reach that albon Bri wasn't able to get in there with his lar scanner to map it 44:24 · it's the part known as the southern Network 44:33 · let's go Mark Leonard needs to steal his courage to venture 44:42 · forth oh boy this is rough 44:50 · [Music] going this is mud brick 44:57 · the walls are made of mud bricks the same as those found on the outside of the pyramid the builders didn't even take 45:04 · the time to cover them with slabs of white Limestone it's clear that work here was left unfinished as if the workers 45:11 · abandoned the site in a [Music] hurry at the end of the corridor Mark 45:17 · manages to thread himself into a tiny room but this isn't yet another burial 45:24 · chamber this is difficult it's get smaller and smaller I 45:29 · believe if I'm not confused we're in the C Chapel of the queen and here we find this amazing 45:38 · Alabaster canopic chest where the internal organs were placed after being removed from the body 45:46 · during mumification the Egyptians had a complicated way of 45:51 · viewing the soul so you think that we have our body our double is made when 45:57 · our body is made and that is called the car a spirit double of your body and 46:03 · throughout your life it exists with you upon your death it inhabits the 46:08 · tomb it was to the car chapels that one would bring offerings for the soul of the deceased after their death once 46:15 · again amenemhat III had been Innovative in placing these chapels for the first time actually in a pyramid a chapel for 46:23 · each of his queens and one for himself this is absolutely amazing to 46:28 · find this incredibly beautiful object still in place and all of this was put 46:34 · in the most inaccessible part of the most inaccessible pyramids 46:40 · ever but after only a few minutes in this CA chamber Mark judges it wise not 46:46 · to linger look at the crack in this chamber 46:51 · this is very serious it's separated several centimeters wide and the uh stones 46:57 · are Bowing in it still looks like it could collapse at any moment I think 47:05 · um I think it's time to [Music] 47:11 · go but in amenemhat III's burial chamber One Last Detail intrigues the 47:19 · egyptologists the lid is beautifully sculpted and intact and relatively un damaged in fact 47:27 · these few chips might be more recent you see in tombs that have clearly been looted where the lid is just shoved 47:33 · aside by the robbers or they simply smashed it but the fact that it's 47:39 · undamaged indicates that the king's burial was never put 47:45 · inside if the lid wasn't smashed by lutters breaking into the Black Pyramid it must have been left 47:52 · open so the sarcophagus was never sealed meaning the pharaoh's mummy could never 47:57 · have been placed inside one thing thus becomes obvious 48:03 · ammat theii was never buried under the Black Pyramid it became very obvious that the 48:10 · pyramid was unstable cracks were forming the ground was sinking up to 3 cm so am 48:17 · him the third had to abandon the project and start a new one he abandoned this um pyramid and decided oh I'm going to have 48:24 · a better one confronted with the failure of this 48:29 · overly complex pyramid the Pharaoh simply decided to have another one built at haara 70 km further 48:39 · south also built of mud bricks this now has a silhouette similar to that of the Black 48:45 · Pyramid but its interior is totally different amenemhat The third's 48:51 · Architects had learned their lesson there was more care taken in 48:56 · ensuring that the haara pyramid was not going to suffer from such um 49:03 · problems here there was no underground Labyrinth one simple Corridor led to a 49:08 · single extremely secure chamber a veritable strong box Made of Stone amhat theii had himself buried at 49:16 · hawar in a pyramid that was perfect for ensuring his eternal rest it was stable solid it met all the 49:24 · requirements that the Pharaoh had set s yet no images exist of this Unique 49:30 · Interior and for good reason Amat theii could not have foreseen the disaster 49:36 · that would eventually strike at his second pyramid it's been totally flooded for 49:42 · over a 100 years because of rising Waters resulting from a canal built close by in the 19th 49:51 · century even if the Pharaoh finally decided not to be buried there dashur Black Pyramid still retains The Prestige 49:59 · of a royal tomb the Black Pyramid did fulfill its funeral role while the king wasn't 50:06 · buried in the pyramid his queens were laid to rest there underground the remains of these 50:12 · two queens of Amat III are still enjoying their Eternal rest but under a precarious pyramid I feel quite bad for 50:20 · these women to be left in the in the sinking cracking pyramid it may not have been quite so G and um 50:29 · situation the failure of the Black Pyramid was in any case a turning point 50:35 · it sealed the fate of pyramids in Egypt the kings were thinking why am I 50:41 · going to build a pyramid if all the stone is going to be stripped away if it's going to be looted king ammat thei 50:48 · is the last Great Pyramid build joser is the beginning amum hat thei is the end 50:55 · and together that is the the era of the Great Pyramids of ancient Egypt while the Black Pyramid may keep 51:02 · on deteriorating in the coming decades this completely unique modeling campaign using the lar scanner means that we will 51:09 · at least have a digital copy exact to the millimeter of its present State the 51:15 · 3D modeling captures the structure for the future even if the whole pyramid now 51:20 · would finally collapse I mean God forbid we don't want that and it would crush all the chambers and Passage ways even 51:27 · if that happened you've now captured the structure that was once there and so that's the value of modeling any uh 51:34 · ancient Monument despite its structural problems 51:39 · and the ravages of time the Black Pyramid is for now at least Still Standing four Millennia after it was 51:46 · built still casting the shadow of am menim hat theii over the Nile Valley

The Muzghuna Pyramids

You became hostile back in August and later defamed me as a harris supporter.
It makes perfect sense now (not that I ever lost a nanosecond of sleep over it).
Hence the reason I wear a backplate.

I find all of the pyramids fascinating. The pyramidion (capstone) for Amenemhat III’s pyramid was actually found near the site. It is made of black granite, ~6’ along each base, enscribed with heiroglyphs, and weighs ~4 tons.
A German Egyptologist found over 80 individual pyramids in the 1840s. To date, over 160 individual pyramid sites have been documented.
I almost used a pic of the pyramidion, it’s amazing that it in particular has survived the ravages of time, vandalism, and conquest. Only four are known, including two cases where the pyramids involved are long gone. :^)
