Arequipa

Arequipa extends along both banks of the Chili River, in the Arequipa or Chili valley. The valley is bordered by the Andes to the north and east and by low coastal hills to the south and west. The city proper extends mainly over 14 districts, while the Arequipa metropolitan area includes 21 conurbated districts.

The site of the city was founded on 15 August 1540, when it was named "Villa Hermosa de Nuestra Señora de la Asunta de Arequipa". On 25 September 1541, by a real cédula issued by Charles V, it became the "City of Arequipa". During the viceregal period, Arequipa gained importance through its economic role and its loyalty to the Spanish monarchy.

Arequipa is Peru's second most industrialized city and one of its most economically active urban centers. In 2024 the Department of Arequipa recorded a nominal GDP of S/31.458 billion and GDP per capita of S/19,593, making it the country's second-largest regional economy.
