The burial chamber of Cheops' sarcophagus. 
This exceptional historical relic is the final resting place of the great pharaoh Cheops,  who reigned during the Fourth Dynasty. The sarcophagus is carved from a single block of solid granite and bears witness to the skill and talent of the craftsmen of ancient Egypt. 
At the bottom right, we can see the granite blocks that blocked the entrance to the pharaoh's tomb, which did not prevent it from being looted.
