Pozo de Banfield

The Pozo de Banfield is a former Buenos Aires Provincial Police station that was used as an Argentine clandestine detention center from November 1974 to October 1978, during the military dictatorship that ruled the country from 1976 to 1983. This detention center was an integral part of what came to be known as the Circuito Camps, and was one of the first to operate as such during the constitutional government of Isabel Perón, nearly 18 months before the 1976 coup d'état. With the nationwide extension of the 1975 annihilation decrees, provincial police forces were placed under the command of the Army, and subsequently the Banfield Investigations Brigade became subordinated to the 3rd Mechanized Infantry Regiment of the Argentine Army.
