Archaeologists using advanced scanning techniques have discovered a previously unknown corridor in one of the Great Pyramids in Egypt. The chamber, measuring 30ft long and over 6ft wide, was found at the Pyramid of Khufu in Giza. Although located near the main entrance, the chamber cannot be entered from the outside, and its use is unknown.
The ScanPyramids project, which was launched in 2015, uses ground-penetrating radar and ultrasound measurements to locate previously undiscovered structures in the pyramids. Once the chamber was detected, an endoscope was fed through a gap in the pyramid to capture images. Scientists are particularly interested in the two large limestones at the end of the corridor, and in any spaces that may lie beyond them.
Mostafa Waziri of Egypt’s Antiquities Supreme Council suggested that the chamber could have been used to redistribute the pyramid’s weight. The previous year, the ScanPyramids project had uncovered a sealed-off corridor in the Pyramid of Khufu, measuring 98ft in length.
The Great Pyramids of Egypt, one of the Seven Wonders of the Ancient World still standing, were constructed more than 4,500 years ago during the Fourth Dynasty reign of Khufu. The ScanPyramids project aims to understand more about the internal structure of the pyramids without resorting to invasive or destructive techniques.
