The National Monuments Service's description

At a point where the bay of Safe Harbour (RO046-004011-) impinges on the NE shore of Rindown peninsula. A bank and fosse extend NE-SW across the peninsula to a pond close to the SW shore (L c. 200m). Its N end is incorporated into the defences of the castle (RO046-004002-), but its S end consists of a broad bank (L c. 100m; Wth 8.5m; int. H at SE 1.1m; ext. H 2m) and a flat-bottomed fosse (Wth of top 18m; Wth of base 11.5m; D 1.5m). The bank declines towards the SW end (Wth 4m; int. H 0.5m; ext. H 1.3m), but the defences enclose c. 20 ha to the SE. The wall (RO046-004018-) is built just to the SE of the bank and parallel with it. The fosse and bank are interpreted by O’Conor et al. (2014, 315-6) as possibly representing the SE edge of the town and providing a boundary with demesne land associated with the castle (RO046-004002-) at the tip of the peninsula.
