Walls and Gateways Edging the Central Piazza to the NW

The walls and gateways edging the central piazza to the northwest are a Grade II listed structure. The wall begins at Trinity, uncoped, and stands approximately 2.2 meters high. It runs northward, following a curve to the east. About 8 meters north of Trinity, the wall slopes down on either side of a vista break featuring sandstone balustrading. Beyond this, the wall slopes down again on either side of a wide opening between two large trees, leading to a raised children's play area with a roughly parabolic plan, which is revetted with rubble.

To the east of this play area is an entrance to the piazza, marked by a pair of widely spaced rusticated, rendered piers that are around 2 meters high and topped with urn finials. A flight of 8 slate steps descends from a cobbled pavement, with simple scrolled iron balustrades on both sides. Adjacent to this entrance, the wall splays inwards to enclose a cobbled seating area approximately 8 meters long, featuring reconstituted stone balustrading and stone flower boxes on top. Terracotta urns are positioned to the right and left of this area.

Immediately to the east, the wall slopes up on either side of a tall baroque archway. This archway consists of a rubble arch with a rendered overthrow shaped like a pediment, flanked by voluted piers. Above the arch on the road side is a central arched niche containing a small baroque statue, with an affixed bronze star above it. On the piazza side, there is a large Coade stone Royal Arms dated 1806, with roundels on the left and right. The wall continues for approximately 6 meters until it joins the Gloriette.
