# Callao District

Callao is one of the seven districts of the Constitutional Province of Callao in the Callao Region, Peru. The Chillón River marks the district's northern border with Ventanilla. On the east, the Callao district is bordered by the Carmen de la Legua-Reynoso as well as the Lima Province's districts of San Martín de Porres and Lima. The Bellavista and the La Perla districts are located to the southeast, while La Punta borders the district on the west. The Pacific Ocean borders the province on the west and south. At 1956, it expanded to the north, encompassing latifunds, lands and estates that belonged to the San Martín de Porres District and the Carabayllo District. During this expansion, the Jorge Chávez International Airport is built.
Since Jorge Chávez International Airport as well as Peru's main seaport are located in this district, Callao is the largest port of entry to Peru.
The city of Callao forms a conurbation with Lima and thus, the district is economically, socially and culturally integrated with this city. (See: Lima and Callao Metropolitan Area).

## Borderline conflicts

In 1956, due to the expansion of the Constitutional Province of Callao over the territory of the Lima Province through Law No. 125382, two conflict zones emerged, one with the Lima District and the other with the San Martín de Porres District. This dispute arose from the imprecision in the wording of the boundaries and the lack of cartography of the law, in addition to the disappearance of the original stone milestones due to the urbanization process. The conflict or indetermination of limits remains in force, as it corresponds to a district-provincial struggle, and is waiting to be fully defined by the Metropolitan Municipality of Lima, the Regional Government of Callao, the Provincial Municipality of Callao, the Municipality of San Martín de Porres, the Presidency of the Council of Ministers and the Congress of the Republic.
