The original ESMA was a complex located at 8151 Libertador Avenue, in the Autonomous City of Buenos Aires, in the "barrio" of Núñez. It was the seat of U.T.3.3.2—Unidad de Tareas (Task Unit) 2 of –which was responsible for thousands of instances of forced disappearance, torture and illegal execution. The military took the babies born to mothers imprisoned there, suppressed their true identities and allowed them to be illegally adopted by military families and associates of the regime. ESMA was the largest detention center of its kind during the Dirty War.
