Aberthaw Lime and Cement Works

Aberthaw Lime and Cement Works is a building constructed from local limestone rubble, featuring red brick dressings around the openings and chimney. It consists of a large rectangular block with two kilns aligned on the seaward side and a mill located behind them.

The kilns have tall, battered walls that rise to about 20 meters and include two semi-circular openings on the west side, along with charge holes on top. These kilns are very large and robustly built, capable of burning 300 tons of limestone at a time, which represented a significant advancement in the lime burning industry. They were charged automatically through a tramway and a tipping device, allowing wagon loads of lime and coal to be delivered directly to the charge holes on top. The structure features a partly damaged machicolated and castellated parapet.

The mill is three storeys high and has a pitched roof, with three windows on the gable ends and six on the long side, each framed with red brick jambs. At the southeast end of the kilns stands a tall square chimney made of red brick, topped with a machicolated limestone cap.

The former engine house, which was located next to the chimney, has mostly been demolished. Inside the kilns, there are firebrick linings and iron doors, along with carefully constructed stone-lined draught tunnels beneath them. The interior of the mill has been dismantled, likely shortly after its closure, leaving the walls as a shell.
