HM Prison Beechworth, now known as Beechworth Gaol, was a medium security Australian prison located in Beechworth, Victoria, Australia.Construction of the current structure was begun in 1859 and completed in 1864 at a cost of 47,000 pounds. The prison closed in 2004 and the site has been purchased by private developers. A replacement facility, the Beechworth Correctional Centre, was opened in January 2005.HistoryHM Prison Beechworth was built on the site of Beechworth's first stockade between 1859 and 1864 at a cost of £47,000. The old Beechworth Prison was designed and constructed by Victoria's Public Works Department between 1857 and 1864.The prison was built in stages between 1858 and 1864 using granite quarried on site. The Beechworth Gaol is one of nine Victorian prisons designed on the radiating 'panopticon' principle which had proved an efficient, cost-effective design for easy surveillance of prisoners by allowing guards to watch over a large area from a central observation point.When opened in 1860, Beechworth provided single cells for 36 prisoners. Accommodation was doubled on the building's completion in 1864. The prison initially housed male and female prisoners, who were kept occupied with work of practical benefit to the town. Between 1918 and 1925 the prison closed from lack of numbers, then operated as a reformatory for habitual male offenders between 1925 and 1951. It became a training prison for straight-sentence prisoners after 1951 until its closure in 2004.Despite numerous minor alterations since 1864 the largely intact features include the cell blocks, observation hall, turnkey's quarters, gaoler's quarters, kitchen wing exterior, warder's quarters, watch towers, perimeter and division walls, the iron entrance gates, entrance court, and yards with the exception of the 1861 female yards which were built over in 1925. Original stairs, balustrades, architraves, skirtings, doors and windows also survive. Slate roofing has been replaced with corrugated iron and louvered ventilators have been removed from cell block roofs. The quarry is a significant feature in the grounds.
