The monument comprises a fort of prehistoric date, visible as upstanding earthworks.

The monument lies on a rocky ridge 420m NNW of Croig farmhouse. Except at its S end, the ridge rises abruptly over cliffs or steep rocky slopes, which maintain an average height of 6m along the E and W sides, and reach a maximum of 10m at the N end; from the S, however, the approach is easy. The remains of what has been a massive wall extend across the S end of the ridge and continue some distance along the W side, but there is no evidence to suggest that it ever continued beyond its present limits.

The fort is thus, in effect, a promontory fort. The maximum dimensions of the generally level area cut off by the wall (the fort interior) are 67m by 30m. A number of stones belonging to the inner and outer faces of the wall are visible, indicating that it had a thickness of up to about 3.7m, and the rubble core is standing in places to a height of 0.6m. The entrance, 2m wide, is on the SSE. Within the interior there are the foundations of what appears to have been a stone-and-turf enclosure of no great age.

Forts of this type are characteristic of the Iron Age (about 500 BC to AD 500).

The area proposed for scheduling comprises the remains described and an area around them within which related material is likely to survive. It is irregular in shape, with maximum measurements of 80m N-S by 50m E-W, as marked in red on the accompanying map.
