Fremantle Prison, sometimes referred to as Fremantle Gaol or Fremantle Jail, is a former Australian prison and World Heritage Site in Fremantle, Western Australia. The site includes the prison cellblocks, gatehouse, perimeter walls, cottages, and tunnels. It was initially used for convicts transported from Britain, but was transferred to the colonial government in 1886 for use for locally-sentenced prisoners.
