Full description

A redan of triangular plan, consisting of a platform with stone faces angled SE and SW, projects from the mid-C18 curtain wall (7906.18) at this location. The site is a Listed Building, Grade I and is Scheduled (h1). This section of the Garrison walls does not appear on the 1741 map (b1). A 1742 plan indicates a proposed line and redan differing from those built (b2). The section of wall with redans built is shown in 1746, but may not have been completed then - the source refers to the 'line proposed' (b3). The redan is marked on Tovey's 1750 map as a 'salient angle' (b4). On a visit in 1990, a central embrasure in each face was noted (h2). The site is 'Redan C' on the 1991 survey (h3). The monument is included in the Schedule.

Described in 1995 (8): The walls are generally 1.8m thick, 1.3m high internally and 2.75m high externally. The steeply battered wall is faced with fairly regular ashlar blocks in courses 0.2m to 0.3m high, with larger blocks along the top and an outward chamfer created by a raised inner coping.

Described in 2005 (9): A well preserved redan with internal and external wall faces of coursed roughly-dressed blocks of various sizes. There is no pointing or through-wall drains. One of the two embrasures points out to sea; the second flanks the curtain wall and Woolpack Battery. The sloping wall top is covered by close-cut grass. The narrow strip of land divided into a series of narrow field plots. These plots were recorded on the 1834 plan as rented out to invalid gunners.
