Two weeks of new thermal scanning in Egypt’s Giza pyramids have identified anomalies, including a major one in the largest pyramid, the Antiquities Ministry has announced.

Antiquities Minister Mamdouh el-Damaty and technical experts working on the project showed the thermal differences in the pyramid in a live camera presentation to journalists.

The scanning showed “a particularly impressive one (anomaly) located on the Eastern side of the Khufu pyramid at ground level,” the ministry said in a statement. The largest of the three Giza pyramids is known locally as Khufu and internationally as Cheops.

The thermal scanning was carried out during sunrise, as the sun heats the structures from the outside, and then during sunset as the pyramids are cooling down. The speed of the heating and cooling phases was used to uncover “hypotheses” such as empty areas in the pyramids, internal air currents, or different building materials used.

“The first row of the pyramid’s stones are all uniform, then we come here and find that there’s a difference in the formation,” said Mr el-Damaty, pointing at the three stones showing higher temperatures.

While inspecting the area, he said they found “that there is something like a small passage in the ground that you can see, leading up to the pyramids ground, reaching an area with a different temperature. What will be behind it?”

He invited all Egyptologists, especially those interested in ancient Egyptian architecture, to join in the research and help come up with ideas on what could be behind the anomalies.
