Arica | Chile

Arica is the capital of the Arica and Parinacota Region in northernmost Chile, located 18 km south of the Peruvian border. Known as the City of Eternal Spring, it features a hyper-arid desert climate with stable, mild temperatures year-round. It serves as a vital port for landlocked Bolivia and a major archaeological hub for the world's oldest mummification traditions.

Historical Timeline

Inhabited for over 7,000 years by the Chinchorro culture, the area was later integrated into the Tiwanaku and Inca empires. Founded by the Spanish in 1541 as San Marcos de Arica, it became the primary silver port for the Potosí mines. Formerly part of Peru, Arica was captured by Chilean forces on June 7, 1880, during the Battle of Arica (War of the Pacific). Sovereignty was permanently transferred to Chile under the Treaty of Lima (1929).

Demographics & Population

The 2026 population is approximately 250,000. The demographic is highly diverse, with a significant Aymara indigenous population and Afro-descendant communities in the Azapa Valley. The economy relies on port services, trans-Andean logistics for Bolivia, and the export of olives and tropical fruits.

Facts & Legends

Legend says the Chinchorro mummies were created because the desert air was so dry that bodies didn't decompose, leading ancient people to believe the dead were still "present" and requiring decoration. A geographic fact: Arica is the starting point for the route to Lauca National Park and Lake Chungará, one of the highest lakes in the world ($4,517$ m). Historically, the Eiffel Cathedral was originally destined for the resort town of Ancón in Peru, but it was diverted to Arica after an earthquake destroyed the city's previous church.
