Convict labour was used to build Richmond's famous bridge and its Gaol. We spent over an hour visiting this historic monument - it was fascinating and awful, and very well presented. You can shut yourself into a solitary confinement cell (no light) and listen to audio descriptions of convict experiences; you can even try on the leg irons in one of the cells - they are surprisingly heavy. Each room was laid out with clear labels and descriptions. Artifacts showed convict life, food and punishment. The entrance fee is excellent value and we would recommend this as an activity for any age group in Richmond.
Bathroom facilities, food and parking are all available in the town centre, less than 5 minutes walk away. There are steps into the Gaol, and inside - although the buildings are all on one level. Wheelchair users would not be able to view this attraction, except from the outside. My husband, with a bad arthritic knee, did manage the few steps up and down into each building.
