While there are many notable museums in Arequipa, the Museum of Andean Sanctuaries (Museo Santuarios Andinos) is one of the best. Visitors can see exhibits that focus on Andes Mountain archaeology and history, such as the world-famous preserved mummy of ‘Ice Princess’ Juanita, a young Inca girl whose remains were only discovered in 1995. Juanita was sacrificed over 500 years ago as part of a Capac Cocha ceremony in which children were sacrificed to appease mountain gods. The child is thought to have been about 11 to 15 years old, and the body is so well-preserved that it has been touted numerous times as one of the world's top discoveries.
Give yourself at least an hour to see everything in the museum, as there is also a short informational video to watch before you explore. Additionally, you’ll see impressive grave tombs, with other mummies found atop Peru's volcanoes and burial artifacts.
