During the military dictatorship of Augusto Pinochet, from 1973 to 1990, Colonia Dignidad served as a special torture center.
In 1991, Chile's National Commission for Truth and Reconciliation concluded that a number of people apprehended by the DINA were held at Colonia Dignidad, and that some of the colony's residents actively helped the DINA torture some of the captives.
Colonia Dignidad's involvement came to light as early as an October 1976 report from the United Nations Ad Hoc Working Group on Chile, as referenced in a March 1977 Amnesty International report, "Disappeared Prisoners in Chile", with the latter report describing the evidence in this way:
 Another DINA detention center described in the [U.N.] document, in which it is alleged that experiments in torture are carried out, is Colonia Dignidad, near the town of Parral…
 Prisoners being tortured in the tunnels under Colonia Dignidad were each interrogated to gain an understanding of their personality in order to gauge the appropriate torture technique.
These techniques led to a number of afflictions lasting indeterminate periods of time.
As many as 100 of the citizens taken to Colonia Dignidad by the DINA were murdered at the colony.
