Boundary Wall Along North Side

The boundary wall along the north side of Grove Road in Portland is a Grade II listed structure dating from the 19th century. It is built of rough coursed rubble topped with a flush rounded coping. The wall starts approximately 20 meters west of No 1, Grove Road, on the opposite side of the road, and extends continuously for about 400 meters to the east, ending at a gate pier at the entrance to Incline Road. The wall stands around 2.2 meters tall, with the upper two courses made of squared stone added later to what was originally a lower wall. There is a break in the construction opposite No 30, Grove Road, where a field boundary indicates the edge of the quarry, marked by a boundary stone featuring an incised anchor, part of a series of Admiralty markers on the island. This wall plays a significant role in defining the character and continuity of the street, which is lined with a continuous row of buildings on its south side. The wall also continues beyond the entrance to Incline Road.
