Puma Punku: Who Really Cut These Impossible Stones?

Inner corners sharp as machine cuts and molten metal poured into stone: how did an ancient culture at 4,000 meters carve Puma Punku without iron tools? High in the Bolivian altiplano, the megaliths of Puma Punku and Tiwanaku have baffled travelers for centuries. Modern claims point to lost civilizations, machining, and alien technology to explain the razor-sharp right angles, modular H-blocks, and metal clamp sockets. But what does the hard geological and archaeological evidence actually reveal? From quarrying volcanic andesite across Lake Titicaca to revolutionary 3D architectural reconstructions, discover the true story of how Andean masons engineered one of the ancient world's greatest wonders.
