Little is known of the archaeological ruins of Puka Pukara, a pink-stone site guarding the road to the Sacred Valley. Some archaeologists believe the complex was a fort—its name means "red fort"—but others claim it served as a hunting lodge and storage place used by the Inca nobility. Current theory holds that this center, likely built during the reign of the Inca Pachacutec, served all those functions. Whatever it was, it was put in the right place. Near Tambomachay, this enigmatic spot provides spectacular views over the Sacred Valley. Pull up a rock and ponder the mystery yourself.
