Walls of Dock Basin (Also known as No 3 Basin)

The walls of the Dock Basin, also known as No 3 Basin, are located at the seaward end of Barry Docks. Construction of Barry Docks began in 1884, and it was first opened to traffic in July 1889. The engineer in charge was John Wolfe Barry, in partnership with H M Brunel, and the contractor was T W Walker.

The dock basin measures approximately 180 meters by 150 meters. The walls are built from large snecked blocks of squared reddish stone, featuring granite coping, dressings, and treads leading down to the water. There is a slipway at the southeast corner. The entrance to No 1 dock on the northwest side has concave recesses for lock gates, which have been replaced with modern versions. The sea entrance also features concave recesses for lock gates, with similar materials used for the return walls on the seaward side.
