Egyptian archaeologists have announced a unique operation that they intend to carry out on December 5. Zahi Hawass will lead a team of colleagues to uncover the main mystery of the Great Pyramid of Giza.

Hawass, former Minister of State for Antiquities Affairs of Egypt, told The U.S. Sun about his upcoming mission. The stone doors of the Great Pyramid have interested archaeologists for a long time, raising serious questions. On December 5, he will lead a team that hopes to solve this mystery, reports Planet Today.

It was Hawass who had discovered the secret doors inside the Great Pyramid. Three of them were found; the first door, with two copper handles, was at the southern entrance to the second chamber. Twenty-one centimeters further back they found a second door, and in the northern tunnel a third one, also with two copper handles.

Several studies have been done on these doors, but they did not answer the main questions: what are they for and what do they hide?

The Great Pyramid of Giza was built in circa 2570 BC for the final resting place of the pharaoh Khufu. It features three chambers, including the “Queen's Chamber” where three mysterious doors are located in two shafts facing each other.

These shafts must be cleared to reveal what lies behind these mysterious doors. One of the theories suggests that they may have been intended for the passage of the pharaoh's soul to the Underworld.
