A hidden corridor nine meters (30 feet) long has been discovered close to the main entrance of the 4,500-year-old Great Pyramid of Giza, and this could lead to further findings, Egyptian antiquities officials said Thursday.
The discovery within the pyramid, the last of the Seven Wonders of the Ancient World still standing, was made under the Scan Pyramids project which has been using non-invasive technology, including infrared thermography, 3D simulations, and cosmic-ray imaging to peer inside the structure since 2015.
An article published in the journal Nature on Thursday said the discovery could contribute to knowledge about the construction of the pyramid and the purpose of a gabled limestone structure that sits in front of the corridor.
