Provinces of Peru

Callao () 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.
