The Great Pyramids of Giza, built in Egypt more than 4,500 years ago, have always intrigued researchers. According to scientists from Italy and Scotland, this underground city is more than 6,500 feet long and 10 times larger than the pyramids.

Using deep-earth imaging technology similar to sonar, the researchers found eight vertical cylindrical structures extending more than 2,100 feet, and several more structures extending more than 4,000 feet deep.
Corrado Malanga from the University of Pisa (Italy) and Filippo Biondi from the University of Strathclyde (Scotland) claim that the discovery could change the understanding of Egyptian history. Nicole Ciccolo, a spokesperson for the project, called it a "groundbreaking study" that opens up new methods for analyzing satellite data and archaeology.
However, many experts have expressed doubts about the accuracy of the research. Professor Lawrence Conyers from the University of Denver, an expert on radar in archaeology, said that this technology cannot scan that deep.
He noted that small structures such as caves or hidden chambers under pyramids are common, and that examples of Mayan pyramids have similar features. To verify the findings, he proposed "targeted excavation".
The Giza pyramid complex consists of three main pyramids: Khufu, Khafre, and Menkaure, named after the pharaohs. Khufu's pyramid, also known as the Great Pyramid, is 480 feet high and 750 feet wide at its base. Khafre's pyramid, located in the center, has been the subject of recent research.
Previously, in October 2022, a study discovered hidden chambers and ramps inside the Khafre Pyramid using similar technology combined with satellite data.
