Fort Dimanche is a former prison in Haiti located near La Saline in Port-au-Prince that was notorious for torture and murder during the reign of François Duvalier.
[1] The original Fort Dimanche was built by the French when Haiti was a colony prior to 1804 and fell into disrepair.
During the reign of Duvalier he and his Tonton Macoutes used the facility as an interrogation center and prison to incarcerate, torture, and murder political opponents.
Dead bodies were often not removed for days and then dumped into mass graves outside the prison.
Gen. Raoul Cédras led a military coup against Jean-Bertrand Aristide in September 1991, Fort Dimanche was turned temporarily into an armory.
