The Museum is housed in the Georgian Corn Exchange and the adjoining, older, Town Gaol. It has an interesting collection of exhibits donated by local people.
The reference section contains parish records, directories and information relating to the town's history. Photographs depict the social history of the town since the early days of photography.
The Museum publishes a local history journal three times a year, and sells various booklets of local interest.
The Museum is staffed entirely by volunteers. Admission is free and there is disabled access. It is open from the beginning of April to the end of September, Monday to Friday, 10:30 am - 4:30 pm.
