The Great Pyramid of Giza is open to ticketed visitors, though access to its chambers and passages is restricted and the wider site has a visible security presence. Research by the ScanPyramids project, launched in 2015, has used ground-penetrating radar and other non-invasive techniques to investigate possible voids and internal structures. Tool marks can be seen on some interior blocks. The pyramid remains largely standing despite the loss of much of its casing, and its sides are closely aligned with the cardinal directions. Claims about carved niches containing a pottery vessel and bone, square tool-marked corridors, unusual air shafts, or crystal formations are not supported by verifiable published archaeological evidence.
