Visiting Villa Grimaldi in Santiago, Chile, left me with much the same chill I felt at Dachau, the former Nazi concentration camp outside Munich. Under dictator General Augusto Pinochet the Chilean military tortured some 4,500 people at Villa Grimaldi. A guide shows visitors the spot where military vehicles drove over the legs of prisoners. Mock-ups of wooden boxes that held as many as six prisoners each, the swimming pool into which detainees were dunked, and a replica of the tower used as a torture chamber and extermination center are all on display. The Muro de los Nombres lists the names of the 226 people killed or “disappeared” by the military at the villa.
