Aberdare Market

Aberdare Market is a building constructed in 1853, featuring coursed rubble with a high plinth and hipped slate roofs adorned with tiled cresting and boarded eaves. The prominent front consists of three bays and showcases classical details in freestone. Above a plain entablature with lettering and the date, there is a pediment with a large blind roundel. Each bay is flanked by paired Tuscan pilasters over the plinth. The windows are horned sash types, with a 20-pane window in the center and 16-pane windows on the sides. The entrance has panelled double doors, although some glazing bars have been removed from the overlight.

To the left, there is a two-storey, three-bay range built in 1903, with a roof that slightly steps up at the corner. This section features cambered voussoir heads over horned 16-pane sashes and a six-panel door with an overlight, all highlighted by tall keystones. Adjacent to this is an enlargement consisting of a single-storey, L-shaped market building. Its tall roof rises to a raised clerestory, which includes an open pediment with a round-arched louvred ventilator, and part of the roof is glazed below the clerestory.

The long façade facing Market Street has a central datestone and features tall, broad semi-circular arched openings on either side, also with tall keystones. Modern glazed double doors are present, accompanied by tall small-pane overlights. The western side has a long six-bay rubble elevation, with a blocked doorway and a tall round-arched doorway at the far end.

On the eastern side, the front wall projects to support the iron gate pier at the yard entrance. Behind this, the side elevation has stock brick dressings and horned sash windows. The main market building extends eastward, forming the short arm of the 'L', and has a two-storey elevation facing the yard. This section features a broken gable with a raised clerestory and a louvered roundel above a central thermal window with small-pane glazing. There are entrances on both sides, similar to those on the Market Street front, although the right-hand doorway has been mostly bricked up. The main north-south range continues a short distance beyond this arm, and the two clerestories are not connected.

The interior has been altered and features a false ceiling.
