By late June 2026, the Giza Plateau had once again captured the world's attention. On June 21, the highly anticipated Giza — The Hidden City — Final Act conference took place at the Centro Congressi Artemide in Castel San Pietro Terme, near Bologna, Italy. Despite the sweltering heat, more than a thousand people gathered in the hall to hear the latest research findings from Filippo Biondi and Corrado Malanga of the Khafre Pyramid Project.
The event's highlight was the presentation of data captured using HarmonicSAR Technology—a harmonic synthetic aperture radar system. The researchers showcased high-resolution Doppler tomographic images which, they claim, clearly delineate the contours of a subterranean structure mirroring the famous Great Sphinx. The team applied facial recognition algorithms to the data and performed a blind test, the results of which, according to the presenters, validated the hypothesis.
Biondi emphasized that the discovery has global implications, stating, "This second sphinx belongs to the people of the whole world." According to him, the find represents a significant piece of ancient heritage that humanity is ready to restore to the collective cultural landscape. The presentation featured images with precise annotations illustrating the location and geometry of the proposed structure in relation to the existing pyramids.
The event served as a logical progression from publications in March and April, when satellite and radar scans first detected an anomaly with a high degree of symmetry. At that time, the probability was estimated at between 80 and 100 percent. This latest presentation provided additional visual evidence and computer analysis results, though, as before, definitive conclusions can only be reached through on-site ground operations.
The conference took place in an atmosphere of intense public interest. The audience comprised both supporters of the hypothesis and skeptics. A full recording of the proceedings with translation has been promised for the near future. For now, the researchers are advocating for caution and a continued scientific dialogue with Egyptian authorities to arrange geophysical surveys and potential excavations.
Each new stage in the exploration of Giza demonstrates how modern technology is revolutionizing the capabilities of archaeology. Radar tomograms allow for a glimpse beneath the layers of sand without breaking the ground, yet it is rigorous on-site verification that will ultimately determine the accuracy of these virtual reconstructions. While the hypothesis of a symmetrical second sphinx continues to receive increasing visual confirmation, the scientific community maintains a healthy skepticism as it awaits the next steps—from in-depth analysis to actual physical expeditions.
The history of Giza continues to evolve, and every new scan brings us closer to understanding the secrets that the ancient plateau still conceals.
