Description
The Towered Gatehouse to Broom Hall is a 19th-century structure designed as a triumphal arch, with the central section elevated as a tower. It is constructed from rubble stonework, featuring ashlar gritstone facings on the lowest storey. The gateway includes a central round-headed carriageway flanked by pedestrian arches, with the eastern arch containing a stair leading to the upper floors. The central arch showcases finely jointed voussoirs, stepped and coursed skew-backs, and a central keystone, with similar arches on the side openings. Above the central arch, a faint inscription reads "R JONES Esqr / 1830," positioned just below a horizontal string course.
The first floor is of equal width for part of its height and features a pair of round-headed windows with 18-pane sashes and colored glass set in lead decorative fanlights. Above the string course, the tower narrows to a square plan, with a similar pair of windows on the second stage. The tower then offsets to the third and top stage, which includes a clock face and two round-headed louvred openings for the upper bell stage. The tower is topped with a pyramidal slated roof and a central weather vane supported by a scrolled iron bracket. The northern elevation mirrors the southern, but the side openings retain their bead-panelled doors and glazed fanlights.
Inside, the first floor contains a square room featuring a carved slate fireplace, a moulded cornice, and a ceiling rose. A stair with plain stick balusters ascends to the second floor, which is unembellished, and from there, another stair leads to the third floor. This level is lined with matchboarding and houses the clock mechanism in a central box, though part of it has been removed for safekeeping. An additional identical stair leads to the bell chamber, where the bells have also been removed. The roof structure consists of king-posts and a single tie beam.
