Wall with Gates and Gate-Piers Together with Ha-Ha and Steps Enclosing Carnes Seat and the Shell House and the Privy

This is a garden wall and ha-ha with gates and gate-piers, likely built in the mid-18th century for the second Duke of Richmond. The wall is constructed from flint with brick quoins and some brick, featuring rounded iron-stone and ashlar coping, along with some replacement brick. The ashlar gate-piers support iron gates. The rear wall, which is approximately 1 metre tall, is partly collapsed. The side walls slope down to create a ha-ha at the front of the garden, interrupted in the center by a double flight of stone steps that rise over an arched niche in front of Carne's Seat. In the center of the rear wall, aligned with Carne's Seat, is a recessed pedestrian entrance, connected by quadrant brick walls to the main garden wall. This entrance features ashlar gate-piers with vermiculated bases, Greek key decoration on the capitals, and pineapple finials, along with a gate that has spiked bars and arrow-finialled dog-bars. There is also a pedestrian entrance at the south-east corner with ashlar piers topped with pyramidal capstones and a later adjacent gateway. A former similar entrance may have existed on the north-west side, where one ashlar pier still remains.
