Summary

This fort is situated on a steep-sided promontory immediately SSE of Over Cassock, but it had been heavily robbed before the middle of the 19th century (Name Book, Dumfriesshire, no.15, p 26). Despite the evident disturbance and erosion, the surviving remains indicate a complex history, probably of at least three phases, though the sequence between the various elements cannot be demonstrated and remains conjectural. The principal element of the fort comprises a rampart reduced to a bank 8.5m in thickness by 1.2m in height, with an external ditch up to 9m in breadth by 0.6m in depth, which have been drawn across the neck of the promontory on the N and are pierced by an entrance. The interior measures at least 80m in breadth at the N end, but it is unclear whether it originally extended to the very tip of the promontory, 150m to the S (0.63ha), or whether it terminated at an isolated arc of rampart that can be seen crossing about 40m short of the end, thus reducing its length to about 110m (0.56ha). If this is the case, the rampart of the fort may have extended along the margins of the promontory in the manner of an enclosure visible within the interior. Apparently representing a separate phase of construction, the bank of the latter, which measures up to 6m in thickness by 1m in height, lies 8m behind the fort rampart on N and in effect blocks the entrance of the fort on this side. Turning down the margins of the promontory on the E and W, it has been eroded by a meander of the burn on the SW, but probably included the isolated arc of rampart on the S into its circuit to enclose an area measuring 83m from N to S by 77m transversely (0.45ha); there are opposed entrances on the E and W respectively, the former with evidence of a worn hollow dropping down the slope outside, and there is also a gap on the S. The third phase of construction comprises a bank and ditch cutting across the S side of this enclosure; separated by a berm 1.8m wide, the bank is up to 7m thick by 0.6m high and the ditch on its N side is 5.5m broad by 0.8m deep. These are of sufficient scale to represent defences in their own right, but it is uncertain whether they were intended to act in unison with S arc of the earlier rampart, simply dividing off an area measuring 40m from E to W by 27m transversely (0.06ha), or whether the interior extended all the way to the tip of the promontory, a much larger area of 0.14ha.

Enclosing Works

A single rampart and ditch cutting off a promontory subsequently probably occupied by a later enclosure, which may have been defensive, and thereafter by another promontory enclosure.

None

Multi-period Enclosure System:
✓   The sequence is conjectural rather than demonstrable. Some are enclosures rather than forts.

Ramparts Form a Continuous Circuit:
✗   This omits the final phase earthwork and it should be borne in mind that where there are two ramparts they are probably successive rather than contemporary.
