The rectangular earthwork enclosure, measuring approximately 100 metres north to south and 58 metres east to west, first appears on Boyd’s Estate Map of 1818, though it was depicted at half its current size. By the time of the 1837 Ordnance Survey six-inch map, the structure had taken on its present dimensions, which remained unchanged through to the 1913 revision of the OS 25-inch map.

The bawn’s construction tells a story of practical fortification; substantial banks of earth and stone define the northeastern, southeastern and southwestern boundaries, whilst the northwestern side features an intriguing double bank with a shallow dip between. The earthwork is particularly well preserved along the northeastern side, where it maintains a sharp profile and displays an outward splay at the corner, which appears slightly raised. A narrow earthen platform runs like a terrace halfway up the outer face of this northeastern bank, perhaps once serving as a walkway for defenders. The tower house, catalogued as WM026-089, adjoins the inner eastern wall at its midpoint, forming the defensive heart of the complex.

Archaeological surveys conducted in 1976 and 1978 found no clear evidence of an external fosse, or defensive ditch, which might typically accompany such structures. The interior slopes gently eastward with an uneven surface scattered with stones, whilst a gap in the northern section of the northeastern bank serves as an entrance. Just outside this entrance stand the ruins of a 19th century house with distinctive yellow brick dressings; local tradition holds that this was a herdsman’s house from when the site formed part of a larger estate, linking the medieval defensive structure to its later agricultural use.
