Archaeologists are very close to locating a secret cavity located within the Great Pyramid of Giza.
Currently, a team of scientists is working to pinpoint the location of the hidden chamber buried within the ancient wonder of the world, according to The Independent. The existence of the space was first detected last October, using non-invasive technology to study the 4,500-year-old monument.
Researchers have turned to cutting-edge technology to locate the mysterious cavity – including 3D reconstruction, infrared thermography and a technique called muography, which records particles known as muons to create images.
"All the devices we put in place are designed to find where the cavity is located. We know there is one, but we're trying to find out where," Mehdi Tayoubi, president of France's Heritage Innovation Preservation Institute told the AFP.
Tayoubi heads the ScanPyramids project and works alongside the Faculty of Engineering at Cairo University.
However, other experts are less certain that a secret chamber has been discovered, according to Newsweek.
Egypt's former Minister of Antiquities Zahi Hawass said that the discovery could just be "anomalies" or "small voids" between the stones.
"The core [of the pyramid] has big and small stones, and this can show hollows everywhere," Hawass said.
Also known as the Pyramid of Khufu, the monument was built between 2580–2560 B.C. during ancient Egypt's fourth dynasty. The now world-famous tourist attraction has been the muse of explorers and archaeologists for centuries.
The caliph al-Ma'mun dug tunnels into the ancient structure in 820 A.D., searching for its secrets. European explorers even used dynamite to blast holes into the pyramid in the 19th century.
Today, tourists who visit the Pyramid complex in Giza can pay a fee to enter an open passageway of the structure and descend into its depths.
