A hidden corridor 30 feet (approx. 9 meters) 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 on Thursday, March 2.
The discovery within the pyramid, the last of the Seven Wonders of the Ancient World still standing, was made under the Scan Pyramids project that, since 2015, has been using non-invasive technology including infrared thermography, 3D simulations, and cosmic-ray imaging to peer inside the structure.
