Walls of upper terrace to N of Llanharan House

The walls of the upper terrace to the north of Llanharan House are a Grade II listed structure. They consist of a low rubble-stone revetment wall topped with a flat-coped parapet on the downhill side. In the center of the wall, there is a semi-circular projection. Toward the eastern end, a raised stone bed is located above which the parapet features openings for climbing plants. To the left of this area, there are stone steps leading from the lower to the upper terrace. Similar stone steps can be found on the western side, flanked by a rock-faced stone wall that includes square piers topped with ball finials, leading to a path from the lower terrace. This flanking wall extends to a doorway in the lower terrace wall.

The semi-circular projection is topped with a stone pineapple on a plinth, which has replaced an earlier sundial. At the eastern end, a return wall is integrated with the rear wall of the terrace, which is built to retain the bank behind. This wall is also made of rubble stone and features three low segmental arches, one of which is blocked, along with a low niche of uncertain purpose. Towards the western end, the rear wall transitions to brick and continues on the western side, where it connects with the brick eastern wall of the former kitchen garden.
