The Town Hall is as a landmark and heritage asset; guided tours of the building, visiting areas not usually open to the public, are occasionally given. Remaining historic features include the old borough courtroom, which has wooden benches and stairs leading down from the dock into the basement – now a storage area but was originally the bridewell (prison cells), located under the front steps. Also accessible only on the tours is the clock tower, entered via 203 spiral steps and which houses the original Potts & Sons quarter-chiming, four faced clock.
