The old Parish Prison was built in the 1830s on the square bound by Orleans, Tremé, St. Ann, and Marais. Conditions were shocking. During the day, prisoners were kept outside in the segregated courtyards. At night, most prisoners slept on the floor of crowded cells with only two blankets each. The last prisoners left in 1895. The location was later used to construct a building for the Sewerage and Water Board.
