Scientists discover hidden corridor in Great Pyramid of Giza

The discovery within the pyramid was made under the Scan Pyramids project that has been using non-invasive technology including infrared thermography, 3D simulations and endoscopes to peer inside the structure.

A hidden corridor nine metres (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 on Thursday.
