One of Australia's most significant convict precincts is only a short walk or Red Decker bus ride from Hobart's CBD (at the 'Old Hobart Gaol' stop).
The Tench, as it was known by its inhabitants, was the convict prisoners' barracks for Hobart Town. It originally spanned over two acres and some 50,000 male convicts passed through the complex. Following the cessation of convict transportation, the site became Hobart Gaol for more than 100 years. This fascinating history can still be discovered in the buildings which remain - a captivating insight into over 175 years of Hobart's shadier past.
