hour of exercise each day. The system was not successful, and considered a dated prisoner management strategy, leading to its removal within five years. New Division was the first building to have electricity, with underground wiring. During World War II, the Australian Army appropriated the division, to keep their prisoners separate from the main population. In 1994 the building was retrofitted to cater for offices, small business premises, and meeting rooms. Women's Prison The north-western complex was originally a service area with a cookhouse, bakehouse and laundry, built in the 1850s. A place for women prisoners was needed following the closure of Perth Gaol and the transfer of prisoners to Fremantle. The buildings were converted to a prison, and a wall built around them, creating Western Australia's first separate prison for women. Population and crime growth led to them being extended in the 1890s and 1910s. The construction of Bandyup Women's Prison saw Fremantle's Women's Prison close in 1970, with the space used for education and assessment until the main prison's closure in 1991. Hospital Built between 1857 and 1859, the hospital was a crucial component of Fremantle Prison. Public works during the convict era relied on convict labour, which could only be provided if the convicts were healthy. From 1886 to 1903, medical services were relocated to the main cell block, with the former building used to keep invalids and female prisoners. The hospital was refurbished and reopened in 1904. It subsequently remained in continuous operation until the prison's closure in 1991. Workshops The original workshop was a blacksmith's shop, one of the first buildings to be constructed on the prison site. Later known as the East Workshops, other workshops included carpenter's, plumber's and painter's, a printing office, and from the 1850s, a metal shop. The West Workshops were built at the start of the twentieth century, providing more work for prisoners through a paint shop, mat maker, shoe maker, book binder and tailor shop. In 1993 the four northern workshops were adapted for use as TAFE art workshops. Tunnels In the 1850s, shafts were sunk into the limestone bedrock to provide the prison with fresh water from an aquifer, and a tank was installed in 1874 to offer the town of Fremantle an alternative water supply. Prisoners worked a pump to fill the tank, which was connected to the jetties through gravity-fed pipes. In 1896, a town reservoir
