The Ilha Grande pest house, located on the coast of Rio de Janeiro state, was built in 1884 to control the spread of epidemics via Brazilian ports. Separated from the continent, the buildings that housed patients could be kept under constant surveillance. Isolation regimens differed in accordance with the class on which passengers had traveled. The complex was used at different times as a military prison and eventually deactivated. In 1942, it was restored and became the Cândido Mendes Penal Colony.
