Key facts

• Vilcashuamán is a pre-Hispanic archaeological complex in Ayacucho, Peru, at about 3,490 metres, and has been declared part of Peru’s Cultural Heritage.
• Archaeological sources document polygonal and dressed stone walls, including the Pachacútec wall associated with the Inca administrative centre.
• A Spanish colonial church was built over part of the Inca wall; the cited sources do not establish a separate megalithic pre-Inca building phase.
• Basalt generally scores about 6 on the Mohs scale and bronze about 3–3.5, but Mohs hardness alone does not prove bronze tools could not quarry or work basalt.
• The video argues that the finest masonry predates the Inca, that the basalt quarry was six kilometres away atop a mountain, and that bronze tools could not shape the stone; the cited sources do not verify these claims.
• Vilcashuamán is commonly translated as “sacred falcon”; the proposed separate pre-Inca name and its function are not established by the cited sources.
