The site is recorded as a walled garden, yet the evidence for any wall is uncertain, and the orchard that once occupied the ground has long since been cleared away. What remains is an outline, a rectangular wooded area of roughly 100 metres east to west and 25 metres north to south, legible on the 1839 edition of the Ordnance Survey six-inch map, and held in local memory as the place where the orchard stood before it was removed.

The broader estate of which this formed a part belonged to Oliver Keating, who held the manor of Kilcowan at the time of his death in March 1629. The manor was a substantial complex for its period, comprising a castle, a hall, an orchard, a messuage (a dwelling house together with its associated outbuildings and land), and at least two cottages. The castle stood at the western edge of the rectangular area now associated with the possible garden. Whether the orchard recorded in the 1629 inventory occupied exactly this same ground, and whether it was ever enclosed by a wall at all, cannot be established with confidence. The designation as a walled garden reflects the possibility rather than the proof.
