Development of the base was authorized by a Congressional bill sponsored by the Minister of War, General
Pablo Riccheri, and signed by President
Julio Roca on 8 August 1901. A site was later chosen northwest of Buenos Aires, for which land was purchased from Eugenio Mattaldi in 1910. Between 1976 and 1982, during the de facto military dictatorship called
National Reorganization Process, there were four secret detention centres inside the base. The most notorious were "La Casita", "Prisión Militar de Encausados", "El Campito" and the "Hospital Militar," where newborn babies were kidnapped from pregnant women among the
disappeared by the regime. The Campo de mayo was also the site of an April 1987 mutiny by Lt. Col.
Aldo Rico and executed by men loyal to him known as
Carapintadas ("painted faces," from their use of camouflage paint). Instigated despite the passage of the
Full Stop Law, which limited prosecutions of nearly 600 officers implicated in the
Dirty War, the incident was tantamount to a coup attempt against President
Raúl Alfonsín, who successfully stayed the mutiny. == References ==
