Summary

Rectangular inland promontory fort with a total site footprint of approximately 0.9ha is positioned on S facing slopes. Promontory projects S towards the confluence of two river systems which are highly visible from the interior of the fort. The flanks are defined by steep slopes of up to 20m at the E, S and W, while on the N there is an earthen bank and external ditch. No obvious entrance feature recorded. There is a circular platform at the N edge the promontory abutting the enclosing elements. Rampart survives well through its length. Interior under scrub and gorse. First map depiction in first edition Ordnance Survey mapping. More detailed earthwork survey in second edition Ordnance Survey maps.
