Sacsayhuamán’s massive limestone blocks bear marks associated with extraction and shaping. The blocks were mostly pounded into shape rather than cut, and the quarry preserves blocks at different stages of preparation. The video argues that the material may be a cast geopolymer and that its marks differ from Aswan’s excavation marks. That is the presenter’s theory, not an established archaeological finding; the green-diorite identification is incorrect.
Sacsayhuamán limestone shows quarrying marks; cast-stone claim is unproven

Key facts
- Sacsayhuamán’s quarry contains massive limestone blocks in various stages of extraction and preparation.
- Surface marks are interpreted as evidence that the blocks were mostly pounded into shape, rather than random, non-functional scrapes.
- The supplied results do not establish that the blocks were cast stone or substantiate the cited 2012 geophysicists’ conclusion.
- The video’s geopolymer and Aswan comparison are the presenter’s theory, not established archaeological findings.
- The stone is limestone, not green diorite.
