Khufu , also known as the pharaoh Cheops (who also built the second pyramid at Giza) had the enormous Sphinx built in his image around 2500 B.C. is the largest of a family of three pyramids on the Giza plateau, on the outskirts of Cairo .It has a structure height of 481 feet, and contains 3.4 million cubic yards of material.Its base covers an area of 13.1 acres, which could accommodate the cathedrals of Florence, Milan, London’s St. Paul’s and Rome’s St. Peter’s and many more.

In exclusive interview with Discovery News , Dr. Zahi Hawass, chief of Egypt’s Supreme Council of Antiquities and also one of the world’s leading Egyptologists, said he will show what lies behind secret doors by the end of the year.

The last remaining wonder of the ancient world , Great Pyramid momument has long been rumored to have hidden passageways leading to secret chambers to where the puzzled over the meaning of four narrow shafts deep inside the pyramid since they were first discovered in 1872.And what the extended shaft might lead to King and Queen afterlife souls lead to ..

Two shafts, extend from the upper, or “Kings Chamber” exit into open air. But the lower two, one on the south side and one on the north side in the so-called “Queen’s Chamber” disappear within, deepening the pyramid mystery.

In 1993 , German engineer Rudolf Gantenbrink sent a robot through the 8 inch square southern shaft which was widely believed to be ritual passageways for the dead pharaoh’s soul to reach the afterlife.After a steady climb of 213 feet from the heart of the pyramid, the robot had to stop in front of a mysterious limestone slab adorned with two copper handles.

In year 2002 , Hawass performed yet again an investigation of the southern shaft on live television. As the world held its breath, a tomb-raiding robot pushed a camera through a hole drilled in the copper handled door and only to reveal another door.

The next day , Hawass sent the robot through the northern shaft. After crawling for 213 feet and several sharp bends, the robot came to an abrupt halt in front of another limestone slab which adorned with similar two copper handles.

“I dedicated my whole life to study the secrets of the Great Pyramid and I must say that these doors create many exciting questions. It is intriguing that the door in the northern shaft and the first door in the southern shaft are equidistant from the queen’s chamber.

“Moreover, they are very similar, as they both feature the same copper handles,” Hawass said.

Speculation abounds that the shafts might lead to a secret chamber which might contain everything: a cache of papyri, a statue of Pharaoh Khufu, or even his real tomb.
