Villa Grimaldi was a complex of buildings used for the interrogation and torture of political prisoners by DINA, the Chilean secret police, during the government of Augusto Pinochet. The complex was located in Peñalolén, in the outskirts of Santiago, and was in operation from mid-1974 to mid-1978. About 5,000 detainees were brought to Villa Grimaldi during this time, at least 240 of whom were "disappeared" or killed by DINA.
