Claims of new ancient structures discovered beneath the pyramids in Giza are greatly overstated.

Claims that researchers discovered previously unknown structures beneath the Pyramid of Khafre — the pyramid situated in the center of the Great Pyramids of Giza — using radar technology circulated online in March 2025.

The purported discovery was that of “five identical structures near the Khafre Pyramid’s base, linked by pathways, and eight deep vertical wells descending 648 meters underground.”

The alleged research behind the claims

The researchers named in the recent claims, Corrado Malanga and Filippo Biondi, did publish a paper and book about their work using Synthetic Aperture Radar (SAR) to explore the Giza pyramid in 2022.

According to NASA, SAR is “a type of active data collection where an instrument sends out a pulse of energy and then records the amount of that energy reflected back after it interacts with Earth.”

However, it does not appear that this research has been peer-reviewed or corroborated by credible archaeologists. Additionally, the research alludes to fringe theories about ancient civilizations and otherworldly intentions for the structures, which aligns with Malanga’s well-documented interest in UFO and alien abduction research as well as Dunn’s “power plant” theory.

Additionally, one of the most popular images being shared in support of the claim, depicting a cross section of the pyramid and the alleged structures, was generated using artificial intelligence (AI).

Further, the Khafre Project does not appear to exist beyond a YouTube channel of a woman named Nicole Ciccolo, who posts frequent unsubstantiated theories about the pyramids. We could find no website or further information about the organization.

So while there have been new discoveries in the vicinity of the Giza pyramids, there is no evidence to support the existence of “five identical structures near the Khafre Pyramid’s base, linked by pathways, and eight deep vertical wells descending 648 meters underground.”
