What is recorded here

Promontory fort stands forty feet above the Atlantic on a triangular headland in the Mullet peninsula, its earthen bank still throwing shadows across the grass though centuries of rain have softened its edges. The western cliff has slipped open like a wound, exposing the old ground level and the vertical slabs that once braced the inner face. People may have watched ships or herded livestock through the narrow causeway near the western end, using the height to see danger before it reached the shingle coves below.

This previously unrecorded promontory fort lies on one of several headlands suitable for fortification along the W coast of the Mullet peninsula. The area is one of gently undulating pasture and sand dunes. The surrounding fields are covered with traces of lazybeds. There is a good view from the site and it is visible from several directions. The promontory fort consists of a triangular SSW facing headland lying 40 feet above sea level, it is defended by a single bank and ditch. The bank is slightly convex to the land and consists of a round topped 4.5m wide bank of earth and stone. Its inner face has been nearly reduced to a scarp averaging only 0.40m high. The external ditch lies 2.5m below the bank at the east, diminishing to 0.90m at the western cliff edge. The ditch is 8m to 10m wide across the base and is U-shaped in section. Several large slabs lying against its inner face may be the remains of a revetting, while a rise in ground level in the base of the fosse near the western end may be the remains of an entrance causeway. The fosse averages 1.5m deep below the outer ground level and there is no counterscarp bank. Recent slippage along the western cliff edge has exposed a section through the defences. This clearly shows the old ground level 0.35m below the present surface, and a bank of earth with a vertical revetting of slabs along the inner face. The interior of the site is nearly level, and except for old cultivation ridges, is quite featureless. It measures 25m in length and is 21m wide. Access to the shingle coves flanking the headland is possible. A larger headland immediately to the E was also defended (MA009-013002-).
