The Ingenious Methods behind the Inca’s Intricate Stone Walls (Video)
Peru's Inca stone walls have long fascinated archaeologists and visitors alike. Made of irregularly shaped stones that interlock so seamlessly that even a razor blade can't be inserted between them, these walls have puzzled researchers for centuries. How did a culture that lacked iron tools build such impressive and intricate walls? What construction methods did the Inca use?
A new explanation has emerged that challenges long-held beliefs. According to this hypothesis, the Inca used a reddish glittery mud, composed mainly of quartz and feldspar, to perfect their stone masonry. This mud allowed the builders to create perfectly jointed stones of different shapes and sizes. The high quartz and feldspar content in the stone structures of Peru supports this theory. The mystery of the Inca stone walls may finally be unraveled, revealing a fascinating story of ancient engineering and innovation.
