Summary

The local SW summit on this rocky ridge, 80m SW from the fort on the very summit (Atlas No. 2881), is also occupied by a small fortification, but in this case its wall has been very heavily robbed. Oval on plan, its interior measures about 25m from NE to SW by 20m transversely (0.04ha). The line of the outer face of the wall can be followed round the whole circuit, standing up to 0.9m high in two courses, and though there is little trace of the wall core, if three stones in a line on the S belong to the inner face, it was originally 4.7m thick. The Scheduling document also suggests there are traces of denuded outworks extending across the SW flank of the hill, though their extent is not recorded in plan and they are not visible on aerial photographs. The interior is featureless and no entrance is visible.
