Unveil

Egypt’s antiquities authorities on Thursday unveiled a newly discovered, sealed-off chamber inside one of the Great Pyramids at Giza, just outside of Cairo, that dates back some 4,500 years ago.

The corridor — on the northern side of the Pyramid of Khufu — was discovered using modern scanning technology. It measures nearly 30 feet in length and is over 6 feet wide, perched above the main entrance of the pyramid.

Egyptian archaeologist Zahi Hawass and the country’s Minister for Tourism Ahmed Eissa, announced the discovery Thursday at an unveiling ceremony outside the pyramid. The Scan Pyramids project, an international program that uses scans to look at unexplored sections of the ancient structure, was credited for the find.
