A mysterious hidden corridor buried deep inside Egypt’s Great Pyramid of Giza has been seen for the first time.
Scientists discovered the passageway in 2016 but did not want to damage the 4,500-year-old monument to gain access to it, so embarked on a years-long project to take a sneak peek at the secrets the cavity might hold.
Using an endoscopic camera and a technique called cosmic-ray muon radiography, experts were able to map the corridor for the first time and confirm that it is 30ft (9m) long and 7ft (2.1m) wide.
They also said it was likely designed to help redistribute the pyramid’s weight around the entrance or another as yet undiscovered chamber.
The 479ft-tall (146m) pyramid, which was built as royal burial chambers around 2560 BC, is the only one of the Seven Wonders of the Ancient World still standing.
