Fort Samaipata is a Pre-Columbian archaeological site and UNESCO World Heritage Site located in the eastern foothills of the Bolivian Andes near Samaipata. The site centers on an enormous sandstone outcrop approximately 250 meters long and 60 meters wide, whose surface has been carved, channelled, and sculpted by successive cultures over more than two thousand years. The complex encompasses structures built by three different civilizations—the Chanè people, the Inca Empire (circa 1470 AD), and Spanish colonizers—making it a unique crossroads of cultural development. The archaeological remains include a ceremonial center on the hill with Inca ritual elements and an administrative residential district to the south, preserving evidence of sophisticated pre-Columbian urban planning and architecture.
