Overview
- New footage from independent researcher Trevor Grassi shows more than 100 narrow shafts cut into limestone around a mound on the northwest edge of the Giza Plateau near the western cemetery.
- Radar engineer Filippo Biondi says satellite and radar data indicate a large subsurface form beneath that mound with symmetry to the known Sphinx, plus patterns he reads as vertical shafts and tunnels.
- Coverage notes Biondi voiced about 80 percent confidence in the interpretation and cited geometric lines from the pyramids and the Dream Stele image of paired sphinxes as support for a mirrored site.
- A Newsweek fact check labeled the viral claim false, former antiquities chief Zahi Hawass rejected the idea, and ex‑colleague Armando Mei publicly said a second Sphinx does not exist and left the project in January.
- Biondi calls for on‑site study with geologists and plans a June 21 presentation in Bologna, while specialists stress that SAR radar methods can misread natural calcarenite voids and that no excavation or peer‑reviewed confirmation exists.
