A favourite unsolved puzzle in archaeology: how were polygonal walls fitted together? The video argues that the method remains unexplained for examples at Alaca Höyük in Turkey and Peru, and to a lesser extent at Delphi, Greece, where it describes the contact surfaces as curved and matched in three dimensions. It says the boulders were too heavy to shift back and forth while fitting and infers that the technique must have been solved another way. The presenter argues that it was achieved more than once, on different continents and arguably in different millennia. The video also says that no explanatory evidence has been found. Awesome and baffling! 🧱🔺
