Bolivia - Fuerte de Samaipata

"The archaeological site of Samaipata consists of two parts: the hill with its many carvings, believed to have been the ceremonial centre of the old town (14th–16th centuries), and the area to the south of the hill, which formed the administrative and residential district. The huge sculptured rock, dominating the town below, is a unique testimony to pre-Hispanic traditions and beliefs, and has no parallel anywhere in the Americas."
