Egypt: First sighting of a hidden tunnel in the Great Pyramid of Giza

(bbc) ⸻ Gyptian antiquities officials have confirmed the existence of a hidden internal corridor above the main entrance of the Great Pyramid of Giza. Video from an endoscope showed the inside of the corridor, which is 9m (30ft) long and 2.1m (7ft) wide. It could have been created to redistribute the pyramid's weight around the entrance or another as yet undiscovered chamber. The Great Pyramid, which is 146m high, was built on the Giza plateau during the fourth dynasty by the pharaoh Khufu, or Cheops, who reigned from around 2609BC to 2584BC. Despite being one of the oldest and largest monuments on Earth, there is no consensus about how it was built. Egyptian archaeologist Zahi Hawass has announced the discovery of a corridor in the pyramid, which could help reveal whether the burial chamber of King Khufu still exists. He also speculated that there might be something important in the space below the corridor, and a second, larger void inside the pyramid was detected using muography in 2017. It is estimated to be 30m long and several metres in height and is located directly above the Grand Gallery.
