Great Pyramid Find: Two Mysterious Cavities With Unusual Features

The Great Pyramid at Giza, Egypt, has long been rumoured to contain hidden passageways leading to secret chambers. Now a team of researchers has confirmed the 4,500-year-old pharaonic mausoleum contains two unknown cavities, possibly hiding a corridor-like structure and more mysterious features.

The announcement by the ScanPyramids project comes at the end of a year-long effort to use various scanning technology on Old Kingdom pyramids, including the Great Pyramid, Khafre or Chephren at Giza, the Bent pyramid and the Red pyramid at Dahshur.

Carried out by a team from Cairo University's Faculty of Engineering and the Paris-based non-profit organization Heritage, Innovation and Preservation (HIP Institute) under the authority of the Egyptian Ministry of Antiquities, the ScanPyramids project used three innovative techniques — muography, thermography and 3-D simulation — to deeply investigate the Great Pyramid of Giza.

An unknown cavity was detected at a height of about 345 feet from the ground on the northeastern edge of the monument, while a "void" was found behind the northern side at the upper part of the entrance gate.

"Such void is shaped like a corridor and could go up inside the pyramid," Mehdi Tayoubi, founder of the Paris-based Heritage Innovation Preservation Institute, told Seeker...read more>>>...

He added that no link can be made between the two cavities at the moment.
