Walls and Revettments to Upper Terrace Garden at Parc

The walls and revettments to the upper terrace garden at Parc are a large raised and walled terrace built on a steep slope in front of the former primary house. The terrace measures approximately 16 meters across and 6 meters wide. It features dry boulder-built revettment walls of a cyclopean nature, which are slightly battered towards the front (downhill side). At their highest point, these walls reach about 5 meters, tapering to a height of around 1.5 meters at the top externally.

In the northeast corner, at the lowest point, there is a primary recess, possibly for a lantern. Within the walled terrace, the walls vary in height from 3 meters at the back to approximately 1.5 meters at the front, with the rear wall serving as partial revettment for the platform where the primary house once stood. A flight of slatestone steps descends into the terraced garden at the southwest corner, and evidence of a second, central flight of steps can also be observed, though it is obscured by later infill. Currently, the ground level of the terrace is about one meter higher than it originally was, suggesting the presence of further archaeological evidence.

At the southwest and northeast corners, the rubble parapet steps up. The southwest corner features a splayed embrasure towards the front, with a small rectangular recess or niche in the return wall to the left. The northeast corner has a similar frontal embrasure and a small rectangular enclosure to the right. Behind this, there is the square base of what is presumed to be a type of tower, with rubble walls surviving to a height of 1 to 2 meters. In the southeast corner, remnants of a stone newel stair can be seen.
