Guild Hall (Including Borough Museum)

The Guild Hall, which includes the Borough Museum, was built in two phases in 1743 and 1773. The materials for the earlier phase were sourced from the sale of features from Stowe, a demolished Charles II mansion in Cornwall, making the building appear somewhat old-fashioned for its time. It is a two-storey structure with a stuccoed exterior, featuring a rusticated ground floor and a slate roof. The upper storey is supported over the pavement by three round-headed arches with keystones. The first floor has four pilasters with Corinthian capitals, and there is a pediment displaying the Royal Arms. The balustraded parapet is adorned with urns, and there is a wooden cupola with a clock and weathervane. The facade includes two cambered sashes with moulded architraves and keystones, and a central niche houses a bust of Hugh Squier, erected in 1910, with a floral wreath below.

The 1743 section contains the Court Room, the Constable's Room, and the Mayor's Parlour. In 1773, a two-storey wing made of stone rubble was added at the rear to create a large dining room for hosting notable visitors, along with a kitchen and other offices below, now known as the Old Assembly Room. Inside the 1743 part, there is an early 18th-century staircase with twisted balusters and dado panelling. The Court Room features a fine bracket cornice, panelling, and elaborate floral and gilded moulding on the architraves, along with original early 18th-century jury benches made by William Puckridge of London in 1743. The doorcases are pedimented with eight fielded panelled doors. The Mayor's Parlour also includes cornices, panelling, and a fireplace, most of which were salvaged from Stowe. The Old Assembly Room boasts a late 18th-century plain marble fireplace and panelling.
