Aradale Mental Hospital was an Australian psychiatric hospital, located in Ararat, a rural city in Victoria, Australia. Originally known as Ararat Lunatic Asylum, Aradale and its two sister asylums at Kew and Beechworth were commissioned to accommodate the growing number of 'lunatics' in the colony of Victoria. Construction began in 1864, and the guardhouses are listed as being built in 1866 though the list of patients extends as far back as the year before (1865).
