The Ballarat Gaol, a former maximum security prison for males, females and children, is located in Ballarat, Victoria, Australia. Replacing temporary structures including prison hulks in the Bay of Port Phillip and holding yards in Ballarat, the gaol operated between 1862 and 1965. The remaining gate, gate house, and cloisters are now home to the Collaborative Research Centre in Australian History (CRCAH) of Federation University Australia.
