CAIRO — 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.
