Key facts

• Qorikancha's inner temple preserves precisely fitted gray andesite blocks laid without mortar.
• The building was converted into a Spanish colonial church, and original Inca masonry remains visible.
• Small stones set between larger blocks have been reported, but describing them as stress-relief markers is a debated interpretation rather than an established fact.
• The video cites similar insertions at Ahu Vinapu, the Osirion at Abydos and Osaka Castle, and argues that they reflect a shared global construction tradition.
• It is not established that these insertions occur exclusively on the oldest megalithic structures, that L-shaped corner blocks wrap and bind adjacent walls in the claimed manner, or that the sites share identical surface signatures.
