Kingston Penitentiary is a former maximum-security facility that operated from 1835 to 2013, holding some of Canada's most notorious offenders. It is now a National Historic Site offering guided tours that detail the history of the Canadian penal system. Visitors access restricted areas including the cell ranges, isolation units, and the prison yard. The facility features neoclassical architecture constructed primarily by the inmates themselves using local limestone.
