Grennan Hillfort.
Grennan Hill Fort. You can just make out the rampart. One of the hardest ones to find yet.
This oval fort is situated at about 500 ft OD on the summit of a rocky hillock; it measures 152 ft NNW-SSE by 62 ft transversely. It is defended by a partly rock-cut ditch, 35 ft broad and 16 ft in maximum depth, starting at the brow of the steep slope on the W, passing round the E side to end on the cliffs in the S. Soil from the ditch forms a rampart above the counterscarp, while a parapet mound crowns the scarp in the N.
A well-defined approach enters into a slight hollow at the lowest point of the interior. An ill-defined outwork flanks the S side of the approach. In the interior are three slightly hollowed circular areas which may be hut sites.
