The slopes overlooking the tiny Peruvian village of Rapayan are dotted with the remarkably well-preserved ruins of an indigenous settlement that predates the Inca conquest. It is a virtual city, complete with homes, a castle, a fortress, mausoleums, murals, subterranean galleries and mummified remains of its ancient inhabitants. As an archeological discovery, it is larger, richer and older than the celebrated Macchu Pichu.
