The Egyptian Sphinx in Giza could be the entrance to an underground “secret city”, according to the latest research by historians.

Malcolm Hutton and Gerry Cannon believe that the Sphinx that sits on the sands of the Giza plateau, in front of the Great Pyramids, could be the gateway to a labyrinth of tunnels and passages and an entire “underground metropolis” that has been lost to the world due to a cover-up by the Egyptian authorities.

The historians explain in their upcoming book “The Secrets of the Giza Plateau and a Second Sphinx Revealed” that news about this lost city first made headlines due to a March 1935 Sunday Express article about the excavations that They were taking place in an underground city that at the time was said to date back 4,000 years.

The couple claims that after that report nothing more was known about this city.

“It was as if all living Egyptologists had lost interest in this wonderful underground metropolis, as all their articles over the next few years focused more on tombs of queens and shafts that had been sunk deep into the ground for funerary tombs.”

Historians believe that a hole in the top of the Sphinx’s head could be an entrance to this lost city, along with other openings in the structure.

However, they claim to have encountered a “wall of pink granite blocks” from the Egyptian authorities.

“There are things down there, tunnels. Many people have written about it but try to cover it all up.

“No one knows what is down there, no one has been able to investigate.

“They’re afraid that if they find things down there, all their books and all their history will fly out the window.

“They started investigating it but then they stopped doing it. They must have known there are things there, but they are worried.

“Once their entire story is proven wrong, all the books they have written will be scrapped. If they have found things, they do not dare to show them.

“There are entries, there are photographs that prove it. There is a hole at the top of the Sphinx, in its head.
