Summary

In a strategic position with panoramic views from the summit, overlooking Howth harbour to the N and Dublin bay to the S, this small contour fort crowns the summit of a natural knoll. The entire site is surrounded by a much denuded stone bank recorded by Westropp in the early 1920's. The bank is presently under dense scrub and heather growth and is not apparent in aerial photography. There are no obvious entrance features visible on the surface. A cairn and a possible barrow have been identified within the interior of the site. The site does not appear on either edition of the Ordnance Survey maps or any other ancient mapping. Westropp (1922, 58-59) described the site in the early 1920's, suggesting that the enclosing elements were more visible.

Landscape

Hillfort Type

Contour fort positioned at the edge of a natural knoll that is defined by steep, exposed rock scarp at the N, W and S. The entire site it surrounded by a much denuded stone bank, hence it being categorized as a contour fort rather than a promontory. The site is strategically positioned with panoramic views from the summit and particularly excellent views of Howth harbour to the N and Dublin bay to the S.

Enclosing Works

The enclosing works are much denuded and obscured by heather and gorse growth. An accurate measurement of its size, therefore, cannot be undertaken. Westropp (1922), however, gives the extent of the fort as measuring 41m by 30m. According to Westropp (1922), a stone wall enclosed the entire site forming a complete circuit.

Enclosed Area:
Area 1:   0.1ha.
Total:   0.1ha.

Total Footprint Area:  Noneha.

Ramparts
