Walls enclosing south car park, about 150 m south of Montacute House

The walls enclosing the former nursery, now part of the car park, are located about 150 meters south of Montacute House and are likely from the 19th century. They are primarily constructed of Ham stone rubble and stand approximately 3 meters high, featuring a thin coping.

The west wall extends northward from No. 1 The Borough and includes an inserted three-centred arch for the main drive. Opposite The Lodge, there is a gateway with a moulded cambered arched doorway set in a hollowed rectangular recess, complete with a boarded and studded gate. A short return northward has a blocked elliptical arch, and the slightly higher wall is lined with brick along the north and east sides, likely for the cultivation of fruit trees. In the northeast corner, there is a small building with a simple window and a pyramidal Welsh slate roof behind a parapet, with eaves that align with the lower east wall. The south wall features a row of upright stones on top as coping, and part of the eastern length may be 20th-century work. A later 20th-century break in the north wall, with plain near ashlar piers, provides access to the main car park. Some sections of the wall may date back earlier, as a rough survey map from 1782 indicates a plot resembling this area.
