Oroncota or Huruncuta was an Inca provincial center or capital on the border of Chuquisaca and Potosi Departments of Bolivia. Oroncota was captured by the Incas during the reign of Topa Inca Yupanqui (1471-1493) and served as a defensive outpost protecting the eastern frontiers of the Inca empire. The primary residents of the Oronta area for more than 1,500 years have been the Yampara people. Extensive and scattered ruins of the Inca and Yampara have been excavated by archaeologists. In the 16th century, during the last years of the Inca Empire and the early Spanish Empire, Oroncota and its region were under heavy attack by the Guarani people (Chiriguanos) who eventually gained control of the area.
