Royal Pump Room Museum

The Royal Pump Room Museum, built around 1842 by Isaac T Shutt, is located on the site of sulphur springs mentioned by Edmund Deane in 1626. The Old Sulphur Well is integrated into the basement of the building, with its previous domed cover from 1807-8 relocated to the Tewit Well. An addition known as The Annexe was constructed around 1913 by Leonard Clark. The building became a museum in 1953.

The museum has an irregular octagonal shape with four projecting side bays featuring Corinthian pilasters on quoins that support an entablature and blocking course. It has an octagonal ogee dome covered with copper tiles, replacing the original leaded roof, and a central lantern. The exterior is made of grit stone ashlar, with pediments above the projections that contain sash windows with panelled surrounds, pediments, channelled aprons, and glazing bars. The recessed faces display an inscribed panel above a doorway with a segmental pediment on console brackets, leading to a 1½ glazed door with margin lights. The Annexe features pilasters that support an entablature, large windows, and a roof with a copper fishtail dormer.

In the basement, the 18th-century stone well-head of the Old Sulphur Well remains in place, complete with the original marble basin, arched openings, and a tented cover. The ground floor interior dates back to 1842 and includes the Pump Room, which features Corinthian pilasters supporting an entablature. Some original thermal fittings and counters are still preserved. Betty Lupton, known as the 'Queen of the Wells', worked here as a well-woman in the early 19th century.

The Crown Hotel is part of a group with Nos 1 to 3 (consecutive) and the Royal Pump Room Museum.
