Old Courthouse (Y Sospan Fach)

The Old Courthouse, also known as Y Sospan Fach, is a two-storey building featuring a gabled main range with hipped wings on either side and an outshot on the south side. It is constructed from coursed rubble masonry and has steeply pitched roofs covered with quarry slate, along with plain close eaves.

The gable end faces Queen's Square and has a raking parapet supported by kneelers, with a hip on the left side. There is a former Venetian window on the first floor, which is now blocked with an inserted lintel. Below this, a tripartite horned sash window has been deepened and narrowed, and there is a modern shopfront at the bottom. The broad doorway is offset to the right, featuring a stone lintel and a modern door.

On the north side elevation, there is a lateral stack, with a slated gablet and offsets, as well as water tabling. The first floor has 16-pane sash windows set under the eaves, while the ground floor features two modern small-paned casements with stone lintels, one of which was added later. A doorway with deep reveals and a modern door is situated between these windows, with two additional modern doorways to the right.

The rear elevation is gabled with a hip on the right side and includes a tall square stack with water tabling. The left side has raking gable copings on kneelers over a canted corner. A central window with a stone lintel is modern, and there is a doorway to the right with a stone lintel, deep reveals, and a 19th-century part-glazed door that leads down to the street.

The south elevation features slightly taller hipped bays flanking a three-window outshot, with modern small-paned windows. The outer bays have enlarged three-light windows, while the outshot has shallow two-light casements under the eaves. The extreme left and center of the ground floor have similar windows flanked by single-light windows, and a deeper two-light window is to the right, accompanied by a doorway at the extreme right with a modern door and steps leading down from the street.

Inside, the ground floor has stone flags, and the ceiling features transverse stop-chamfered beams, likely from the 17th century, along with similar mantel beams. There are some traces of timber framing on the south side, and the roof is supported by through purlin collared trusses.
