Summary

A heavily reduced enclosure is situated in a coniferous plantation on the crest of a rounded hill NW of Thirlestane. Described as an irregular oval on plan, measuring internally about 67m from NNE to SSW by 54m transversely (0.27ha), its defences had already been heavily reduced before it was first recorded by James Hewat Craw in 1912. The SE sector was missing, and though the rampart was at best a stony bank 2m in thickness by 0.6m in height, on the SW it was accompanied externally by a second. Nothing is visible beneath the trees in the interior and the position of the entrance is unknown. While at face value relatively slight, its hilltop position, size and the presence of other stone-walled forts in the vicinity, argue for it inclusion as a defended site.

Investigation History

This is conceivably the concentric ring on a hill symbol shown to the NW of Snawdon on Andrew and Mostyn Armstrong's Map of the County of Berwick (1771), though in relationship to the 19th century farmstead of that name it lies SW.
