A popular theory frames Machu Picchu as a military checkpoint controlling Amazonian access to the Inca Empire, but evidence challenges this. The site has only one known gated entrance, lacks typical Inca fortifications, and features precise megalithic masonry unlike the quick rubble construction seen at actual military sites like Vilcabamba and Choquequirao.
