Summary

This coastal promontory is situated c. 5km SW of Durrus town on the W coast of Co. Cork. It can be described as a small oval area (23.6m NE-SW; 13m SE-NW) barely projecting N into Dunmanus Bay at an altitude of 8m OD. The promontory is depicted on the first edition OS six-inch map (1842) as a circular enclosure. It has an overall site footprint of 0.08ha. Westropp notes that the fort 'once defended a longer headland, a deep bank of drift on low rocks and 24 feet high, that has since crumbled away since 1840, when the maps show it projecting nearly its own depth beyond the present edge' (1915, 283). The neck is defended by an earthen bank, 5.2m in height and an external ditch with a depth of 2.65m. Westropp (1915, 283) noted a dry stone revetment to bank which is no longer visible. The bank and ditch are crossed by a causeway c. 2m wide which leads into the interior of the site to the S. The internal area is now reduced in size to less than half that area recorded on the first edition OS map and much of it is now overgrown with scrub. Westropp (1915, 284) noted a collapsed souterrain (CO130-024002-) 'close to the dangerous edge'.

Monument Condition

Westropp noted that the fort 'once defended a longer headland, a deep bank of drift on low rocks and 24 feet high, that has since crumbled away since 1840, when the maps show it projecting nearly its own depth beyond the present edge' (1915, 283). Much of the defences on the SE survived intact. The N face of the promontory is nearly perpendicular and presents itself as an unprotected front exposed to the sea.

Investigation History

Depicted on first edition OS-map as circular, hachured area. Surveyed by Westropp who noted small headland defended by a curving earthen bank with a dry-stone revetment and external ditch. He also observed an external path that led to a spring/well and rocks below the promontory (1915, 283). Subsequent visitation by the Cork Archaeological Survey in 1985 who noted that the stone-facing of the bank was no longer visible.

Interior Features

There were no recorded internal structures within the interior of the site, however, Westropp notes a possible collapsed souterrain 'close to the dangerous edge' (1915, 284).

Water Source

While there is no evident water source inside the enclosure, Westropp notes an 'old, narrow path scaling the very steep slope up to the north end of the fosse where it 'touches a little spring'. He suggested that this was the 'water-path of the fort-dwellers and a means of securing shellfish and fish' (1915, 1283).

Entrances

Single break in the bank on the S side with a rough casueway across the fosse. This break measured 2m in width. This is possible an original entrance to the site, however without excavation, this cannot be confirmed.

Enclosing Works

The neck is defended by an earthen bank, 5.2m in height and an external ditch with a depth of 2.65m. Westropp (1915, 283) noted a dry stone revetment to the bank which is no longer visible. Bank and ditch crossed by causeway (Wth 2m) to S.

Surface Evidence

Westropp noted dry-stone revetment to the bank and a possible 'cap-wall'. He observed that only the 'ledge and a few blocks remain of the stone-work' (1915, 284). The defences are much overgrown
