Grosmont Town Hall

Grosmont Town Hall is a small 19th-century building that features an upper assembly room and a ground-floor arcaded market place. It is constructed of rubble stone with ashlar dressings. The southeast front has a prominent large center gable that slightly projects forward. The gable head includes a small square louvred window, which was formerly glazed, and a stone cross at the apex. Flanking the gable are narrow recessed side walls with tall chamfered slits on both the ground and first floors. The tops of these walls are capped with a flat coped parapet.

Between the second and attic floors, there is a projecting string course supported by shaped kneelers. The first floor features a three-light wooden transom window with moulded mullions and chamfered stone jambs. Wide steps lead up to a broad segmental arched opening on the ground floor, which was originally open but is now enclosed by 20th-century boarded double doors. The market hall is located to the northwest, where the ground floor forms an open arcade with large segmental arched openings and iron gates on three sides. The northwest gable has a similar three-light transom on the first floor. The northeast elevation features two similar transoms on the first floor along with a central tablet commemorating the Duke of Beaufort's gift of the Town Hall to the parish in 1902.

On the southwest side, there is an external stone staircase leading to a porch with a gabled roof, and a lock-up cell on the ground floor has a small barred window. The paved market area is surrounded by open arches on three sides. At the northern end, there is a large octagonal stone with triple quatrefoils on each face, resting on a plain base; this stone is believed to be the base of a cross, the remains of which are found in the churchyard. The first-floor assembly room consists of five bays with arch-braced collar trusses, and the roof is ceiled at the collar with two square cast iron ventilators. There is a lateral fireplace with a shouldered head and moulded stone surround, and the entrance doorway features a plank door with applied fillets.
