Summary

Multiple enclosure surrounding summit at the NE end of a hill ridge overlooking the Derg river valley to N. The site has a total footprint of approximately 1.55ha. It comprises an inner enclosure approximately 50m in diameter within a collapsed stone wall 1m high, which may be an Early Medieval ringfort (Chart 1940, 228) and eccentric outer oval enclosure with a bank 5m wide and 0.5m high. To the NNW a third enclosure is visible apparently springing from the oval enclosure on the W & NE respectively. There are a number of entrance breaks in all three of the enclosing elements, although it is unknown if any of these are original. At least three rectangular houses are apparent within the interior. Ramparts survive well throughout their circuit. Outer rampart partly levelled on the N. The complex layout of the enclosing elements may suggest that they are not contemporary (Chart 1940, 228).

Entrances

Six breaks in the enclosing elements. A single break in the inner enclosing element comprises a simple but wide break in the bank at the W. Three breaks in the middle enclosing elements at the S, SW and W comprise simple gaps. Two breaks in the outer enclosing elements consist of simple gaps in the bank. It is not known if any of these entrances are original.

Enclosing Works

Enclosure approximately 50m in diameter is surrounded by a collapsed stone wall 1m high. This may be an Early Medieval ringfort (Chart 1940, 228), surrounded eccentrically by an oval bank 5m wide and 0.5m high. To the NNW is a third enclosing feature which joins the oval enclosure on the W & NE respectively.

Enclosed Area:
Area 1:   0.19ha.
Area 2:   0.62ha.
Area 3:   1.5ha.
Total:   1.5ha.

Total Footprint Area:  1.55ha.
