The permanent exhibition begins with an explanatory preamble about what dictatorships are and the dismantling of a whole series of myths that the propaganda machine of the Rafael Trujillo regime created and rooted in the Dominican collective belief. The exhibition continues with a chronological journey with the preceding events from 1916, with the occupation of the United States in the Dominican Republic. Then it proceeds to show the Trujillo dictatorship and the Joaquín Balaguer dictatorship that ended in 1978.
