Until now, experts wondered how it was possible that in the middle of the Neolithic period, more than a thousand years before the first pyramids of Egypt were built, these enormous stones could be moved and placed with millimetric precision, orienting them towards the sunrise for astronomical purposes. The 32 stones that make it up weigh about 1,140 tons. Of these, the largest — and the one that covers the back of the chamber — weighs 150 tons. This is the largest slab that was moved during the megalithic phenomenon in the Iberian Peninsula and the second-largest in Europe.

According to a Phys.org report, a team of archaeologists, historians, geologists, and physicists led by José Antonio Lozano Rodríguez of the Canary Islands Oceanographic Center and the University of Alcalá examined the Menga dolmen, a megalithic monument built in what is now southern Spain some 6,000 years ago, to learn more about how it was constructed. The structure consists of stone walls topped with a stone ceiling supported by stone pillars. Some of these stones weigh more than 160 tons. The researchers suggest that the stones were quarried about one-half mile away and transported to the site on sledges dragged...

An Egyptian archaeological team discovered the remains of the sixth-century-B.C. structure three years ago during excavations at an archaeological site in the ancient city of Buto, now called Tell Al-Faraeen, in Egypt's Kafr El-Sheikh governorate...Unlike traditional monuments, which typically have a single pylon, the observatory had two pylons facing each other, framing the circular observatory spot and symbolizing akhet, or the horizon where the sun rises. Facing this Akhet was a limestone watchtower that was likely once paired with another and used to observe constellations, Ghonim said.The excavation also uncovered a statue of the falcon-headed god Horus. The depiction of...

I recently came across the fact that Stonehenge had a fence. Or lets call it a Palisade. Theorized to be at the time of the placement of the megaliths. So what was this Palisade for?The Unsolved Mystery of The Stonehenge Fence | 11:25Paul Whitewick | 135K subscribers | 4,451 views | August 25, 2024

Cosmos Magazine reports that the Altar Stone at Stonehenge, which weighs more than six tons, may have been transported to southwestern England from Scotland. The Altar Stone currently rests under two toppled sarsen stones at the site. Anthony Clarke of Curtin University and his colleagues analyzed the composition of the minerals in the Altar Stone with mass spectrometry, and found that it has a distinct chemical fingerprint matching rocks in Scotland's Orcadian Basin, which is located more than 460 miles away. "Given its Scottish origins, the findings raise fascinating questions, considering the technological constraints of the Neolithic era, as to...

After 20 years, excavation work at Orkney's Ness of Brodgar will come to a close at the end of this week (16th August).Over the last two decades, this sprawling dig in the heart of Orkney's World Heritage Site has become one of the most important archaeological projects in the world. It has revealed a huge complex of Neolithic buildings covering three hectares, with more lying undisturbed across this ancient landscape.Finds have included beautiful decorated and painted stones, polished axe heads, carved stone balls, and even human and animal bones. But more than that, the excavation has changed the way we...

A fingerprint left on a clay vessel made by a potter 5,000 years ago has been found in Orkney.The print was discovered on a surviving fragment of the object at the Ness of Brodgar archaeological site.Archaeologists have been excavating at the complex of ancient buildings in the Heart of Neolithic Orkney World Heritage Site since 2006.Imaging technology was used to reveal the fingerprint left after the potter pressed a finger into wet clay.Ness of Brodgar is the University of the Highlands and Islands (UHI) Archaeology Institute's flagship excavation site.The potter's fingerprint was noted by ceramics specialist Roy Towers, who was...

Did humans truly transport these massive stones from Wales, or could a far more natural force be responsible?...The massive bluestones, each weighing several tons, might not have been laboriously hauled over 200 kilometers by Neolithic people, as widely believed, but were instead delivered to the Stonehenge site by the relentless forces of ice.

A pair of climate protesters was arrested Wednesday after allegedly spraying the Stonehenge monument in England with orange paint, according to local authorities. The protesters, from the group Just Stop Oil, sprayed the monument with orange paint Wednesday, one day ahead of the Summer Solstice, the longest day of the year in the Northern Hemisphere, the environmental activist group said in a statement on the social platform X. The two individuals were “demanding the incoming government sign up to a legally binding treaty to phase out fossil fuels by 2030,” Just Stop Oil said. Wiltshire Police told The Associated Press...

Environmental protesters sprayed paint on Britain’s Stonehenge on Wednesday, with orange marks covering some of the stones of the prehistoric megalithic structure on the eve of the summer solstice celebrations. Two people have been arrested on suspicion of damaging the ancient monument, police said in a statement. “This is extremely upsetting and our curators are investigating the extent of the damage,” English Heritage, the charity that manages Stonehenge, said on X. Stonehenge remains open, it added. The monument, one of Britain’s most visited tourist spots, also holds spiritual significance and attracts thousands of revellers, spiritualists and tourists during the summer...

The Antikythera Mechanism, widely believed to be the world’s first computer, was among wreckage retrieved from a shipwreck off the coast of the Greek island Antikythera on May 17, 1901. A year later, it was identified as containing a gear by Greek archaeologist Valerios Stais. Since then, the Mechanism has had a lasting impact on scientists and thinkers across the world.

In this video, I visit Avebury Henge and Stone Circle ... the largest in the world 🤩 Built and much altered during the Neolithic period, roughly between 2850 BC and 2200 BC, the henge survives as a huge circular bank and ditch, encircling an area that includes part of Avebury village. Within the henge is the largest stone circle in Britain - originally of about 100 stones - which in turn encloses two smaller stone circles.The history books state it was built for ceremonial purposes, but they forget to take into account the geological data. If they did, they would...

Global warming has slightly slowed the Earth’s rotation — and it could affect how we measure time. A study published Wednesday found that the melting of polar ice — an accelerating trend driven primarily by human-caused climate change — has caused the Earth to spin less quickly than it would otherwise.

Explanation: Discovered by accident, this manuscript page provides graphical insight to astronomy in medieval times, before the Renaissance and the influence of Nicolaus Copernicus, Tycho de Brahe, Johannes Kepler, and Galileo. The intriguing page is from lecture notes on astronomy compiled by the monk Magister Wolfgang de Styria before the year 1490. The top panels clearly illustrate the necessary geometry for a lunar (left) and solar eclipse in the Earth-centered Ptolemaic system. At lower left is a diagram of the Ptolemaic view of the Solar System with text at the upper right to explain the movement of the planets according...

Archaeologists from the University of Wyoming (UW) have uncovered a megalithic plaza in the Cajamarca Basin of northern Peru.According to the researchers, the plaza dates from around 4,750 years ago and is one of the earliest examples of a circular plaza construction in the Andean South America.The discovery was made at the Callacpuma archaeological site, consisting of two concentric walls of large, vertically placed megalithic stones held upright without the use of mortar.The form and size of the construction, alongside the absence of domestic items to indicate habitation, suggests that the monument was likely ceremonial in purpose.A study of the...

The remnants of a bronze age tomb once thought to have been destroyed and lost to history have been discovered in County Kerry on the Atlantic coast of Ireland.The tomb, known locally as Altóir na Gréine – the sun altar – stood for approximately 4,000 years on a hill outside the village of Ballyferriter on the Dingle peninsula before vanishing in the mid-19th century...Georgiana Chatterton, an English aristocrat and traveller, had visited the site and sketched the monument in 1838, but 14 years later an antiquarian named Richard Hitchcock reported that it had been broken up and carried away, presumably...

Chisel marks on a stone uncovered in Rupinpiccolo protohistoric hill fort from north-eastern Italy were suggested to be a representation of the night sky (Bernardini et al. 2022 Documenta Praehistorica XLIX). The patterns of the 29 marks are analyzed here to establish if they reproduce popular stellar asterisms. Nine marks are found to match the Tail of Scorpius and five the Orion's Belt, together with Rigel and Betelgeuse. Nine marks are found in the approximate position of the Pleiades showing some match with the cluster members. On the back side, 5 marks possibly reproduce Cassiopeia. One mark slightly North of...

For thousands of years, our ancestors found solace in the winter solstice. Today, that belief is still reflected in the astonishing sight of the sun setting on Orkney's Maeshowe tomb. Located 10 miles off Scotland's north-eastern coast, the Orkney islands are a treasure trove of history, from the famous Neolithic village Skara Brae to the hauntingly beautiful Ring of Brodgar – a spellbinding stone circle that was a site of ritual and ceremony. However, when I visited another of Orkney's famous prehistoric sites, the Maeshowe tomb, my first impression was of an unremarkable green mound surrounded by a ditch. Despite...

Located near Antequera in Malaga (Andalucia, Spain), Menga is part of a UNESCO World Heritage site consisting of three dolmens constructed between 3800 – 3600 BC. It is one of the largest megalithic structures in Europe and was built on the top of a hill with giant rocks. It is renowned for its enormous orthostats or vertical stones, one of which weighs nearly 150 tons...Using petrographic and stratigraphic analysis techniques, the researchers discovered most of the stones were calcarenites... The researchers write in their paper that moving and building a dolmen from such large, massive but fragile stones would require...
