HM Prison Geelong

The gaol was built by prisoners who slept on high security barges on Corio Bay during construction. The three-storey central block is cruciform with east and west wings serving as cells, the north wing as an administration block, and the southern wing as a kitchen, hospital and a tailoring workshop. The Australian Army used the prison as a detention barracks during, and for a few years after, World War II.

The government closed the gaol in 1991 and the site now operates as a museum. It is open to the public on Saturdays, Sundays and daily during public and school holidays. The gaol remains mostly unchanged. A gallows exhibit recreates the 1863 hanging of James Murphy, who battered Constable Daniel O'Boyle to death at the Warrnambool court house. Cell 47 is of special interest as it contains a mural painted on a wall by a prisoner, titled Window of Freedom. In 2021, buildings constructed in the 1970s were removed to restore the site to a more historic look.
