The origin of its name is unknown; both Indian (particularly Yunga, or Coastal Peruvian) and Spanish sources are credited, but it is certain that it was known by that name since 1550.
Callao is built on and around a peninsula, the district of La Punta, a wealthy residential neighborhood. An historical fortress, the Castillo de Real Felipe stands on the promontory overlooking the harbor.
Residents of Callao are known as chalacos.
