Info from Wikipedia
The Colchester Arts Centre, is an arts centre in Colchester, Essex, which is located in a former Church of England parish church, the church of Saint Mary-at-the-Walls, a name derived from its proximity to the Roman town walls.
The empty church building was converted to an arts centre, opening its doors in 1980. It is the venue for a variety of artistic, entertainment and community events, including live music, comedy and a regular farmers' market.
