• The chamber was uncovered by the Scan Pyramids Project, although not accessible from the outside. 
• Archaeologists are clueless about its function.

Egypt recently discovered a newly sealed-off chamber inside one of the Great Pyramids at Giza, the outskirts of Cairo dating back 4,500 years ago.

Ahmed Eissa, the Minister of Tourism and Antiquities, and Egyptian archaeologist Zahi Hawass reported the discovery on Thursday, at an unveiling ceremony outside the pyramid.

Measuring 9 meters – almost 30 feet in length and 2 meters – more than 6 feet wide, branched above the main entrance of the pyramid, the corridor sited on the northern side of the Pyramid of Khufu was uncovered using modern scanning technology.

An international program known as the Scan Pyramids project was acknowledged for the discovery. The program uses scans to explore unexplored sections of the ancient structure.

However, the chamber is not accessible from the outside as archaeologists are uninformed of its function.

The unveiling ceremony was also graced by scientists from the Scan Pyramids Project which started in 2015. 

At the unveiling, Christian Grosse, a member of the project said that several scanning techniques were deployed to uncover the chamber such as ultrasound measurements and ground penetrating radars. 

He added that “there are two large limestones at the end chamber”, but they do not know what is behind the stones and below the chamber.

The Pyramid of Khufu is one of three pyramids that make up the Great Pyramids at the Giza complex. It was named for its builder, a Fourth Dynasty pharaoh who ruled from 2509 to 2483 B.C. The Egyptian pyramids are the only remaining examples of the original Seven Wonders of the World.
