Italian Fringe Researchers Claim to Find Massive Structures Beneath Giza

​Social media blew up over the last two days with a wild claim that Italian archaeologists discovered a massive underground series of structures beneath Khafre’s pyramid on the Giza Plateau. Numerous postings alleged that ground-penetrating radar had discovered eight cylindrical spiral structures stretching around 650 meters beneath the pyramid and are connected to two vast cube-shaped rooms eighty meters on each side. On the upper end, they connect to a series of five chambers identical to the King’s Chamber in Khufu’s pyramid, but hidden in Khafre’s. According to the researchers behind the claim, this was merely a part of a massive underground city.

​The story spread quickly thanks to a video about an alleged press release last weekend by Italian researchers Corrado Malanga, Armando Mei, Filippo Biondi. Greg Reese, a former InfoWars figure with an unreliable track record. The video appears to use A.I.-generated narration.
 
Biondi and Malanga had previously used synthetic aperture radar doppler tomography to identify an alleged internal structure in the Great Pyramid in 2022. The 2022 paper seems to be the only actual bit of published work related to the supposed claim. Malanga is an Italian UFO researcher who concluded “aliens” are actually interdimensional parasites that “hijack” human souls. Armando Mei is an Italian author of conspiracy theory books about a predynastic lost Egyptian civilization. Filippo Biondi previously promoted a “harmonic” investigation of Khafre’s pyramid last year using a new technology he claims to have requested a patent for. Biondi is a former academic who left his university to become a full-time remote sensor specializing in promoting the “hidden” truths of Khafre’s pyramid.
 
The researchers claim that a full report will be out in the coming days. They provided the following summary to a group of pseudoarchaeology and paranormal social media personalities: 

​Abstract of the Conference on March 16, 2025
 
This abstract summarizes the key points of our research, which aimed to clarify the possible hidden structures inside the second pyramid of the Giza Plateau, known as the Khafre Pyramid. This research was conducted using non-invasive techniques based on publicly available Synthetic Aperture Radar (SAR) data, provided as open-source by Capella Space (https://www.capellaspace.com) and Umbra (https://umbra.space).
 
First Step
Our study was inspired by previous research conducted, described, and published by Filippo Biondi and Corrado Malanga. That research, focused on analyzing the internal structures of the Pyramid of Khafre, led to the publication of a book and a scientific paper. It revealed numerous internal structures within the first pyramid of the Giza Plateau, uncovering the presence of rooms and corridors both above and below ground level. This research utilized Synthetic Aperture Radar (SAR) technology, which, for the first time, employed an innovative and original software developed by Filippo Biondi. This software allowed the transformation of the radar electromagnetic signal into phononic information, capable of detecting millimetric displacements of vibrating structures inside the analyzed structures that had remained completely invisible until then. The tomographic images obtained through this methodology led to the construction of a model of the Pyramid of Khufu, of which we present four reconstructions below.
 
Second Step
In the second phase of our research, we decided to focus the radar analysis on the second most important pyramid of the Giza Plateau, the Pyramid of Khafre. This pyramid provided a wealth of data regarding previously unknown internal structures. The tomographic images obtained from the satellite data processing immediately highlighted the presence of 5 structures located at the center of the pyramid, above Belzoni's chamber, which contains a presumed sarcophagus mistakenly believed to be the Pharaoh's tomb. These structures share the same shape as the so-called Zed structure found inside the Pyramid of Khufu, above the ceiling of the so-called Pharaoh's or King's Chamber. The 5 Zeds appear to be connected by geometric pathways, and alongside these structures, additional secondary structures are visible from various satellite angles, as shown in some of the tomographic images below. The analyses of these data, obtained using entirely non-invasive techniques, are briefly summarized below. These findings allowed us to construct a 3D model of the entire complex. The examination of dozens of tomographic images obtained from different angles, using Capella Space and Umbra radars, enabled the 3D reconstruction of most of the objects inside the Pyramid of Khafre. Below, we present some images from our 3D analysis.
 
* Analysis of the structures above Belzoni's chamber: intensely colored spots can be observed, appearing in all tomographic images taken from different angles, corresponding to internal artificial structures.
* Improvement of the signal-to-noise ratio revealing the internal structure of the 5 Zeds, consisting of 5 horizontal levels and a sloping roof
* Tomography with another cross-sectional line showing the presence of vertical structures located
 
As observed in the 3D model, below the ground level (ground zero) of the main structure, vertically aligned cylindrical structures extend for hundreds of meters beneath the Giza Plateau. Notably, eight of these structures, arranged in two parallel rows from north to south, descend to a depth of 648 meters, merging into two large cubic structures measuring approximately 80 meters per side. These fea
tures are illustrated in the tomographic images and 3D models presented below.
8 cylindrical structures identified in our tomographic images appear as vertical wells, hollow inside, surrounded by descending spiral pathways.
 
Third Step
The next phase involved analyzing the tomographic data to determine the full extent of the underground structures beneath the Giza Plateau. The tomographic images clearly reveal that structures exist beneath the plateau, extending below the pyramids of Khafre, Khufu, and Menkaure (Mykerinos) for approximately two kilometers beneath ground zero. As seen in the tomographic data, which places the Pyramid of Khafre at the center, with Khufu's shadow on the right and Menkaure in the upper left, these structures form a vast area of non-natural constructions following complex geometries. In the fourth step of our investigation, these structures will be further analyzed, with the possibility of excavation to verify the artificial nature of the structures we have identified.
 
* Panoramic South-North view of the Giza Plateau with a tomographic line cutting through the Khafre structure at approximately half of its height. The darker central line corresponds to the edges of the Khafre Pyramid (Northeast and Southwest), which have low vibrational content and therefore appear darker. The various bright spots beneath the pyramids represent artificial structures located approximately 2 kilometers below the pyramid plateau.
