Aberthaw Lime and Cement Works

Built of local limestone rubble with red brick dressings to the openings and chimney. Large rectangular block with two kilns in line on the seaward side and the mill behind. The kilns have tall (about 20m) battered walls with two semi-circular openings on the west side and charge holes on top. A pair of very large and massively built lime pot kilns, which brought a new scale of working to the lime burning industry, being able to burn 300 tons of limestone at a time. The kilns were charged automatically via a tramway and a tipping device, which brought waggon loads of lime and coal directly to the chargeholes on the top. Partly damaged machicolated and castellated parapet. The mill is three storeys and had a pitched roof. Three windows to the gable ends and six to the long side, each with red brick jambs. Tall square chimney at south east end of the kilns. This is red brick with a machicolated limestone cap. The former engine house, which stood beside the chimney, has largely been demolished.

Kilns lined with firebrick, iron doors; carefully constructed stone lined draught tunnels under the kilns. The interior of the mill was dismantled, presumably soon after closure, and the walls are a shell.
