Summary

What have previously been described as outworks to the oval dun crowning the summit of this rocky and steep-sided ridge are unusually extensive, enclosing an irregular area measuring 72m from NE to SW by up to 22m transversely on the SW (0.12ha), and are possibly the remains of a fort with its entrance on the SW. A second wall springing from its perimeter provided additional protection on the SW. Two level platforms in the NE end are possibly the stances of timber round-houses, and there is also a depression ringed with rough stones and choked with reeds that may be the site of a well. The only other features visible within the interior are two more recent stone founded structures within the SW end. While the dun shows evidence of vitrifaction, no trace of vitrified stone has been observed in the outer walls. The dun measures 16.5m by 12m within a wall from 2m to 3m in thickness.
