Black Castle (in ruin)

Situated on a rocky promontory SE of the present harbour, separated from the land at the W by a deep rock-cut fosse, with a steep drop to the sea on the other sides. The earliest reference to the castle is in 1174 in a grant from Henry II to Earl Richard (Clarke 1944, 1) and it later formed part of the medieval borough of Wicklow (WI025-012----). It may occupy the site of an earlier promontory fort. A 'rampart' indicated on the OS 6-inch maps further inland is not now visible at ground level. The keep is triangular in shape and was constructed of uncoursed rubble. A wall (max. present H 1.2m) survives along the W side (E of the fosse) with a central gap (Wth 1.5m) reached by a small flight of possibly modern rock-cut steps. At the junction of the W and SE walls are the remnants of a roughly quadrangular corner tower (H c. 4m) which extends beyond the line of the W and SE walls. Two loops survive, a small one in the S face and a larger one at SW. The SE wall of the castle (of which only the lower courses remain) is built on a plinth and survives to a height of 3.5m at the E (seaward) end. It contains a garderobe chute below which a small gully has been cut into the rock towards the sea. The wall (max. ext. H 2.8m) is curved and there is a doorway (Wth 1.2m) just above the junction with the SE wall. The interior of the site is very uneven, but there are traces of a rectangular structure (probably modern) in the SW corner, cut into the rock.

The Black Castle was likely built in the late 12th century, with the earliest recorded mention in 1174, and may have been constructed by a local lord or as part of Norman expansion in the region. Its strategic location on a rocky promontory suggests it played a defensive or administrative role, controlling access to the harbor and surrounding area.
