Summary

What may be the last remnants of a fort can be seen on a promontory forming a narrow finger projecting WSW from the coastal escarpment on the N side of Drumbreddan Bay. Heavily eroded along both sides, the interior measures about 42m in from ENE to WSW by between 12m and 5m transversely, and is cut off at the landward end by a ditch 6m in breadth by Im in depth; probably modified from a natural hollow in the crest of the promontory, There is no trace of a bank on either lip of the ditch.

Investigation History

First noted by George Wilson (1885, 63), the fort appears on the 2nd edition of the OS 6-inch map and is described in the County Inventory for Wigtownshire (RCAHMS 1912, 151, No. 432). It was subsequently re-surveyed by the OS in 1972 and visited by RCAHMS in 1955 and 1984. It was Scheduled in 1938
