Summary

This small fortification is configured as a promontory work on the northern of two rocky bosses immediately N of East Laroch. The boss falls sheer on the NE and SE, while access across the gentler approaches from the NW and SW is blocked by two roughly concentric walls, the upper of which has been drawn around the margin of the summit on this side to enclose a triangular area measuring about 36m from E to W by a maximum of 27m transversely (0.05ha). The entrance faces W midway along the arc of defences. The featureless interior is largely bare rock
