Footbridge and boundary wall on N side of Leighton Hall

The structure consists of a footbridge and boundary wall located on the north side of Leighton Hall. The footbridge features a walkway with a boundary wall extending east and west, which includes flights of steps. It is constructed from coursed, rock-faced Cefn stone with ashlar dressings. The single-span bridge has a pointed arch adorned with two orders of roll moulding and displays Naylor's monogram in quatrefoils within the spandrels. There are four pairs of buttresses on each side, with each pair having a single base and topped with saddleback copings. The open parapet features pointed quatrefoils and includes four alcoves on each side, corresponding with the buttresses, which have slate benches, some of which are damaged.

On the southwest side of the bridge, there are half-turn stone steps leading from the deck to a lower level. The parapet has ramped coping. The boundary wall is a retaining wall with a noticeable batter and a low parapet with ramped coping. To the west of the bridge, the wall extends for approximately 110 meters and includes one flight of stone steps, with an octagonal enclosure at the western end. To the east of the bridge, the wall continues for about 50 meters and features four flights of stone steps, with a circular enclosure at the eastern end.
