A 30 feet long hidden corridor has been discovered close to the main entrance of the 4,500-year-old Great Pyramid of Giza. According to Egyptian antiquities officials, the discovery could lead to further findings.
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.
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.
The Great Pyramid was constructed as a monumental tomb around 2560 BC during the reign of the Pharaoh Khufu, or Cheops. Built to a height of 146 metres (479 feet), it now stands at 139 metres and was the tallest structure made by humans until the Eiffel Tower in Paris in 1889.
