Description
The Harbour yard walls and gates to Greaves Wharf and Oakleys Wharf consist of a wall approximately 65 meters long, made up of several sections that clearly indicate different phases of construction. At the northeast end, there is a rubble stone wall that connects to Oakleys, which has been breached to create an entrance to Cwrt yr Harbwr. To the right of this entrance, the attached wall curves and is built from large blocks of coursed stone, topped with stone coping and featuring a pedestrian gate. Between Cwrt yr Harbwr and Wharf House, there are three sections of wall with entrances marked by monolithic gate piers, with the northernmost section still retaining its iron gates.
