One of Bolivia's most important arqueological sites and listed as a world hertiage site by UNESCO for the massive stone carving that makes up its core. In the pre-Incan era, the Chané culture used the space for ceremonial purposes. When the Inca took over the lands, it was transformed for military uses. Later, in the colonial period, the Spanish built the fort and village near the temple. The stone work extends 250 meters long and 60 meters wide, and includes carvings of serpents, pumas and jaguars.
