The present Lewes prison was opened in 1853, but there were earlier prisons in the town.
A prison on North Street was opened in 1793. After the new prison was opened in 1853, this North Street prison became a military prison, used to keep Finnish (Russian) prisoners of war during the Crimean War, and later as a naval prison. The building survived into the second half of the 20th century.
Before that there was a house of correction in the Cliffe built in 1610. Before that the Town Hall cellars are supposed to have been a prison used to incarcerate the Lewes Martyrs, prior ro their burning; the West Gate was used as a prison, and earlier still the Castle dungeons.
