[PHOTOS] Two Mysterious 'Secret Chambers' Discovered Inside Egypt's Great Pyramid

Two secret chambers have been discovered in Egypt's 4,500-year-old Great Pyramid of Giza.

Researchers confirmed they had found the mysterious cavaties after scanning the centuries old tomb using revolutionary radiography equipment.

The Scan Pyramids project made the latest discovery after being able to demonstrate the efficiency of non-evasive Muons technology at the Bent Pyramid in Dahshour this May.

Last year thermal scanning identified a major anomaly in the Great Pyramid, sparking a debate over whether there was a long-running network of tunnels hidden away inside.

But now the mystery has been answered as the Ministry of Antiquities announced on Thursday that 'two anomalies' were found in the pyramid built under King Khufu.

They are now looking to conduct further tests on the 146m-high monument to determine their function, nature and size.
