Deep in the Osiris Shaft, a subterranean hall has a central rock island ringed by a precisely carved canal. A massive granite sarcophagus sits at center, its lid alone weighing 11-12 tons and stretching 9 feet! The chamber lies 100-115 feet beneath Giza. 19th-century visitors noted water just 4-6 inches above the floor — designed to fill without flooding. 💧⛰️
