Vilcabamba (in Hispanicized spelling) or Willkapampa (Aymara and Quechua), often called the Lost City of the Incas, is a lost city in the Echarate District of La Convención Province in the Cuzco Region of Peru. Vilcabamba, in Quechua, means "sacred plain". The modern name for the Inca ruins of Vilcabamba is Espíritu Pampa (Plain of the Spirits).
Vilcabamba was the capital of the Neo-Inca State from 1539 to 1572. The Neo-Inca State was the last refuge of the Inca Empire until it fell to the Spaniards and their indigenous allies in 1572, signaling the end of Inca resistance to Spanish rule. Subsequently, Vilcabamba was abandoned and its location forgotten. In 1911 explorer Hiram Bingham mistakenly identified the abandoned ruin of Machu Picchu as Vilcabamba, but he also visited a ruin called Espiritu Pampa by local Peruvians. In 1964, Gene Savoy identified Espiritu Pampa as the fabled Vilcabamba, a designation widely accepted by archaeologists and historians.
