Fragile? That's not a word I would ever use to describe the Great Pyramid.
I think that should probably be “fragile contents of the chamber”.
"May fears time, Time fears the pyramids." -- old saying
The corbels at the top of the grand gallery have been found to ba hanging on by a fraction of an inch on one end, suggesting the structure was exposed to major stress such as an earthquake of unusual strength. OTOH, it may have happened during the event that cracked the granite blocks used to roof the King's Chamber and the relieving chambers above it.
Mostly it's a crazy local control obsession. The backlash from Hawass and Lehner against the idea of the internal ramp, and even of the muon study, was breathtaking. Since his partial rehabilitation, Hawass has been trying to strip the debris layers away to reach bedrock in the Valley of the Kings -- something that btw has never been done in modern times -- in his desperate attempt to make a big score and find an unplundered pharaonic tomb.
The top step of what must be a tomb entrance was spotted about 120 years ago, and has never subsequently been excavated, mentioned, or catalogued, but I'm not sure most Egyptologists know how to read modern languages.
What Goes Up - Alan Parsons Project
What goes up, must come down
What must rise, must fall
And what goes on in your life
Is writing on the wall
If all things must fall
Why build a miracle at all
If all things must pass
Even a miracle won’t last
What goes up, must come down
What must stand alone?
And what goes on, in your mind
Is turning into stone
If all things must fall
Why build a miracle at all
If all things must pass
Even a pyramid won’t last
How can you be so sure?
How do you know what the earth will endure?
How can you be so sure?
That the wonders you’ve made in you life
Will be seen
By the millions who’ll follow to visit the site
Of your dream?
What goes up, must come down
What goes round, must come round
What’s been lost, must be found
