The archaeological site of Santa Rosa de Tastil in the province of Salta, Argentina, features the well-preserved, pre-Inca stone foundations of one of the country’s largest pre-Hispanic settlements. The complex consists of compact stone houses without windows and narrow alleys. The ruins cover 17 hectares in the Quebrada del Toro gorge at an altitude of around 3,200 metres and form part of the Qhapaq Ñan (Inca road system), which is protected as a UNESCO World Heritage Site. The settlement is thought to have been inhabited between the 14th and 15th centuries, prior to the full-scale Inca expansion, and could have accommodated up to 3,000 inhabitants. – Argentina – 1975
