It measures roughly 28.5 metres north to south and 20 metres east to west, defined by a low earth-and-stone bank and a surrounding fosse, that is, a shallow ditch, which varies noticeably in character as it circles the site: narrow and relatively deep along the straight western edge, broader and barely scratched into the ground to the east. Inside, a curving stony wall or tumbled structure follows the line of the outer bank, and a small stone-lined annexe sits at the northern end. None of this adds up to a defensive or agricultural purpose in any obvious way. What it does suggest is something more deliberate and decorative, a feature built to be looked at, walked through, or perhaps simply to frame a view.

The Ordnance Survey maps offer the clearest clue to its origins and transformation. On the 1840 six-inch map, the site appears as a square field, a fairly ordinary parcel of land. By the 1920 edition, the same spot is shown as a small oval copse of trees, which matches closely what survives on the ground today. The broader landscape around Cappaduff contains a cluster of 19th-century additions: named groves, plantations, gardens, and even recorded badger burrows, all of which point to a period of deliberate estate landscaping in the area. The enclosure appears to belong to that same impulse, the shaping of a countryside to produce variety, incident, and controlled wildness within what was otherwise working pasture. The fosse along the western side may have been deepened for drainage, a practical adjustment folded into what was otherwise an aesthetic project.

Today the site is in pasture and the fosse is largely obscured by fallen branches. The bank is barely legible on the south-eastern side and two gaps, one at the north and one at the north-west, break its circuit without ever having formed a formal entrance. A fallen tree lies across the southern interior. The views to the north and west that presumably made the spot worth developing in the first place are still there, open across the slope, even as the enclosure itself quietly continues to disappear back into the ground.
