Recent high-resolution scans beneath the Giza Plateau suggest a vast, engineered subterranean complex featuring pillar-like structures, deep vertical shafts, and cylindrical formations that do not resemble known tombs or burial architecture. Independent researchers argue the layout implies advanced ancient technology, possibly dating to a pre-dynastic or pre-civilisation culture, with theories proposing an energy-generation or resonance system linked to the pyramids above. Some interpretations draw on Sumerian texts, suggesting knowledge attributed to the Anunnaki—beings said to have guided early human civilisation and technological development. With excavation forbidden and access sealed, the structure remains hidden beneath Giza, standing at the centre of one of the most controversial ancient-technology debates in the world.
