Prison design

Between 1926 and 1931, the Cuban government built four such panopticons connected with tunnels to a massive central structure that served as a community centre. Each panopticon had five floors with 93 cells. In keeping with Bentham's ideas, none of the cells had doors. Prisoners were free to roam the prison and participate in workshops to learn a trade or become literate, with the hope being that they would become productive citizens. However, by the time Fidel Castro was imprisoned at Presidio Modelo, the four circulars were packed with 6,000 men, every floor was filled with trash, there was no running water, food rations were meagre, and the government supplied only the bare necessities of life.
