Old Mount Eden Prison is a former jail on Boston Road in Grafton, kept as a historic site so people can see the buildings where Auckland's prisoners were once held. It is a place for understanding how the city dealt with its offenders, and the story is told through the stone buildings themselves rather than through a modern attraction. It sits on the Mount Eden side of Maungawhau, one of the city's volcanic cones, so the setting is as much part of the visit as the prison. Our pick for anyone who wants a serious look at Auckland's justice history in Grafton.
