The prison was originally built to house transported convicts from Britain and was later used to incarcerate local offenders as well. The prison was known for its strict discipline and harsh punishments, including solitary confinement, hard labor, and flogging. It was also the site of several significant events, including a riot in 1988 that resulted in extensive damage to the prison.

Visitors to Fremantle Prison can take guided tours of the site, which include the main cell blocks, exercise yards, and punishment cells. There are also tours that focus on specific aspects of the prison's history, such as its use during World War II as a military detention center.
