Arequipa is located in southern Peru at around 2,400 meters, at the foot of Misti volcano. The Spanish founded the city on August 15, 1540. Its center is almost entirely built from Sillar, a white to pink volcanic rock that earned it the nickname "White City." Since 2000, its historic center has been a UNESCO World Heritage site.The most important sight is the Santa Catalina Monastery, founded in 1579 and, covering around 20,000 square meters, is like a small city itself with alleys, courtyards, and colorful walls. The Museo Santuarios Andinos displays the mummy Juanita, an Inca girl found in 1995 on the summit of Ampato volcano. Enjoy views of Misti and Chachani from the Mirador de Yanahuara, with its Sillar arches.
