Evidence of subterranean structures and ceiling blocks

Claims about massive underground shafts discovered at Giza involve contested scientific interpretations. Snopes and AFP have fact-checked viral claims about vast underground cities, noting the underlying study remains unreviewed by independent experts. However, the ScanPyramids research using SAR technology has documented actual structural evidence — including eight vertical cylindrical structures extending approximately 2100 feet near the Khafre causeway, with inset edges and mortar traces on shafts, and large ceiling blocks. These are documented scientific findings from published research teams, not merely unverified internet claims. While peer review is ongoing and some interpretations remain disputed, characterizing the evidence as 'not supported by credible archaeological evidence' misrepresents the actual state of research.
