An incredibly important pre-Colombian and even pre-Inca civilization archeological site, with traces of human habitation that date back more than 10,000 years. This fortified city that at its peak housed over 2,000 inhabitants was originally built by the Omaguaca tribe around the 12th century. Unfortunately not everything is original / preserved, but part of the Pucará was rebuilt in the last centuty (it was re-discovered 1908) and a monument "in the style of the stone houses" was even added in 1935 to commemorate the archaeologist who first excavated the land. The location was strategically chosen to be easily defensible and to provide good views over a long stretch of the Quebrada de Humahuaca and the views are still spectacular today. The Pucará de Tilcara was declared a National Monument in 2000, and is the only publicly accessible archaeological site in the Quebrada de Humahuaca. Highly recommended!
