The Moor’s Prison in Piazza San Marco, Venice was built in the 12th century. Located near the Doge’s Palace, it served as a prison for non-Christian prisoners, primarily Moors from North Africa and Iberia. The prison was used until the mid 16th century when it was replaced by more modern prisons. It is believed that prior to its use as a prison, the building may have been part of a Byzantine structure or possibly a public bathhouse.
