The Prison Gallery is located at the northern end of the Gatehouse entry. It was opened in July 2004 to facilitate the sale of Prisoner Art.
The establishment of the Gallery provided the opportunity for the Prison to host a variety of different exhibitions that have a relationship or connection to the history of the site. To enable exhibitions of historical artefacts to be displayed, humidity controlled air conditioning to museum standard was installed in 2006.
The Prison Gallery has provided a new dimension and an interesting revolving display in the free admission public area of the Prison.
