History of Fremantle Prison: The history of Fremantle Prison, a former Australian prison in Fremantle, Western Australia, extends from its construction as a prison for convicts, using convict labour, in the 1850s, through to its modern-day usage as a tourist attraction.  The design for Fremantle Prison was based on the Pentonville Prison in Britain, and it would be the longest, tallest prison cell block in the southern hemisphere.  Construction began in 1851, and was completed by the end of 1859.  The prison was transferred to the colonial government in 1886 for use for locally sentenced prisoners.  Following a Royal Commission held in 1898−99, some changes were made to Fremantle Prison, including knocking down the inner wall between two cells, introducing a prisoner classification system, and constructing internal walls in the main block to create four separate divisions.  A new cell block, New Division, was completed in 1907 and occupied in 1908.
