Opened in 1841, the gaol closed its doors to prisoners in 1988 and now fills with curious visitors. Highlights include the grim hanging tower, cell blocks, grave area, displays of artifacts, plus the colonial architecture and gargoyles. Visitors can wander around as they please, or take one of the regular guided tours offered on Sundays from 11a to 3:30p. A souvenir shop sells postcards, mugs and trinkets. The gaol is found in the western Adelaide parklands near the River Torrens. Last entry to the gaol is admitted at 3.30 pm and one can explore the gaol on Sundays with a tour guide only.
