The gallery has a temporary exhibition programme and a programme of activities for young people. It is open from Tuesday to Saturday.
The building adjoins a local library. On this site, Charles Babbage, the Victorian mechanical computer pioneer, was born in 1791, although the original house has been demolished. A blue plaque records his birth.
On 25 March 2013 a fire seriously damaged the museum and library and destroyed some artifacts, including relics of the city’s Roman period. The museum now remains closed while restoration works commence, which the council says 'will take several years'. All artifcats have been moved to alternative locations following the fire.
