Summary

This small promontory fort lies on the SW side of a much larger promontory forming the coastal escarpment to the S of Float Bay. The promontory projects SW into a narrow point, while the defences cut off the level approach from the NE. Partly ploughed-down, they comprise up to five ramparts and ditches, but these probably represent several periods of construction, the innermost ditch and its external rampart probably being a discrete phase; this ditch is up to 5.5m in breadth by 0.9m in depth and cuts off a triangular area some 35m in length from ENE to WSW by a maximum of 19.5m transversely (0.05ha). About 8m outside it is the first of a belt of four close-set ramparts with external ditches, which cut off a much larger area about 50m in length (0.14ha). These ramparts vary between 3m and 1.8m in thickness, and the accompanying ditches 3.4m to 2.5m in breadth, the broadest of them being the outermost, a hint that these too represent several successive defensive schemes. A gap in the defences on the ENE marks the entrance.

Investigation History

Mapped but not annotated on the 1st edition of the OS 6-inch map, the fort was first drawn in detail for the Wigtownshire County Inventory (RCAHMS 1912, 150-1, No. 430, Fig. 90), and subsequently re-surveyed by RCAHMS in 1955. It was Scheduled in 1938 and revisited by RCAHMS in 1984.

Enclosing Works

Almost certainly at least two defensive schemes here, the inner represented by a single broad ditch and external rampart, the outer by a belt of four ramparts with external ditches, but itself possible representing several phases of construction.

Enclosed Area:
Area 1:   0.14ha.
Total:   0.14ha.

Total Footprint Area:  3.0ha.

Ramparts

None

Multi-period Enclosure System:
✗   Not demonstrably multiperiod, but spacing and the variable breadths of the ditches suggest several periods, the innermost enclosing no more than 0.05ha.
