Yanahuara District is a suburb within the city of Arequipa, Peru. Yanahuara is well known for its buildings built from sillar, a pearly white volcanic rock. At least 1/4 of the district's area is taken by "Umacollo", where various middle-class residential houses of the city are located. Yanahuara includes the popular avenue strip known as the "Avenida Ejército", where many banks and modern offices are also located. Its surroundings contain various well-cared churches of the Spanish-colonial era, as well as public parks and the well-known "el mirador e iglesia de Yanahuara", a popular spot where tourists concur to view the city and its background volcanoes.
