Callao (Spanish pronunciation: [kaˈʎao]) is a seaside city and constitutional province in Peru. Located next to the Pacific Ocean, it forms part of the Lima metropolitan area alongside Lima province. Its autonomous status dates back to 1836, when it was declared a Littoral Province of the Peru–Bolivian Confederation, after which it was declared a Constitutional Province by the government of Ramón Castilla in 1857.
Callao is Peru's chief seaport and home to its main airport, Jorge Chávez International Airport. Founded in 1537 by the Spaniards, the city has a long naval history as one of the main ports in Latin America and the Pacific, having been a vital Spanish town during the colonial era. Central Callao is about 15 km (9.3 mi) west of the Historic Centre of Lima.
