The Guildhall

The Guildhall is a building dating primarily to 1773, with earlier elements. It functions as a guildhall and has a four-window front, incorporating a lower, narrower eastern unit and a western porch. The building is single storey with a basement, constructed of rendered stone under slate roofs, with a stone stack at the east end of the main range. The gabled porch at the west front is built of dressed stone. The entrance is marked by an elliptical arch of voussoirs, now containing late 20th-century steel gates, accessed by nine stone steps flanked by plain iron railings. A stone plaque above the arch reads "Guildhall / Rebuilt 1773," and a carriage lamp is fixed to the apex. Inside the porch, double boarded doors lead to the main hall. A stone tablet is fixed to the north wall, with an arched head and an inscription relating to the Right Hon. John Lord Cardiff and Mr William Dav. A small slate plaque commemorates Sir David Evans, Lord Mayor of London 1891-2, born at Glanmychydd Farm, Llantrisant.

The north side features six-over-six-pane horned sash windows set within segmental stone heads and stone sills. Below these, at basement level, are full-height round-headed openings with raised surrounds, containing hornless six-over-six-pane sash windows with side lights; the right-hand opening has a planked door with overlight. The narrower eastern unit houses a six-over-six-pane sash window, illuminating the clerk's office.

The south side includes a small, rubble lean-to with a boarded door. A projecting side stack, now truncated to eaves level, is centrally positioned on the south wall of the main hall, with no window openings. The eastern unit includes a planked door under a segmental head, accessed by an external stone staircase. The east gable end has a small, blind window with a flat head and stone sill. Below is a planked door under a segmental head and a blocked window opening, both accessible through a small, roofless brick enclosure.

The main hall has a picture rail and 20th-century benches flanking a central aisle. A small clerk's office and toilet occupy the rear of the eastern unit. The basement storey is not accessible from within the building, instead entered via an external doorway on the north side. It comprises four bays divided by pilasters and moulded cross beams. A small kitchen is located within the eastern unit.
