Exterior

The Town Hall owes its present impressive appearance to Penson. His are the tall windows and central pediment as well as the extension to the rear, with rounded corners (the infill to the SW is of 1933). The effect is harmonious and convincing: Penson showed real sensitivity in the additions he made which respect the building’s Georgian character. He retained the round arches on the ground floor: these remained open until they were glazed in 1906. The cupola was  added in 1929.

Interior

The ground floor, with plain, cast-iron columns, is still used as a market hall. The rearward extension contains a stone staircase with simple detailing, reminiscent of Penson’s stairs at Montgomery Gaol. It leads up to a fine assembly room, the former court room. The compartmented ceiling and pilasters along one wall seem likely to be Penson’s design.
