Fremantle Prison is a former Australian prison located in The Terrace, Fremantle, in Western Australia. The 60,000 m² (15 acres) site includes the prison, gatehouse, perimeter walls, cottages, tunnels, and prisoner art.
The prison was built by convict labour in the 1850s, and transferred to the colonial government in 1886 for use as a gaol for locally-sentenced prisoners. It closed as a prison in 1991 and reopened as a historic site. It is now a public museum, managed by the Government of Western Australia. One of the notable features is the preservation of art and graffiti on the walls in some cells. (Fremantle Prison is also known as Fremantle Gaol.
