In 1975, by a direct order from Pinochet, the military created the secret service, the DINA. They chose as their torture operating headquarters a place called Villa Grimaldi, located on the lower slopes of the Andean Mountain range, in the Peñalolen valley, near Santiago. It had been a beautiful Villa, with a history of wealth and with close ties to powerful Chilean elites. It was here that the overall strategy for repression and systematic elimination—physical and political—was thought out and refined in the most important years of the dictatorship. During the years of full operation, from 1975 to 1978, close to three hundred people are believed to have disappeared from Grimaldi and more than five thousand men, women and children were tortured in Terra Nova / The Palace of Laughter, as the “special personnel” of the torture center baptized it.
