A roughly circular enclosure, approximately 36 metres in diameter, shows up on aerial photography, its outline still legible despite centuries of agricultural activity. What makes it stranger still is that cultivation ridges, the kind left by repeated ploughing or spade-work, run directly across its interior in a north-north-west to south-south-east direction, suggesting that at some point the enclosed space was turned over to farming, its original purpose either forgotten or simply no longer relevant to whoever worked the land.

Circular enclosures of this kind are scattered across the Irish midlands and beyond, and they can represent many different things: a ringfort, which was a farmstead of the early medieval period enclosed by an earthen bank; a cashel, its stone equivalent; or something older still, whose function is now impossible to determine without excavation. The overlying cultivation ridges point to a long subsequent history of use, the enclosure absorbed into the wider pattern of the landscape rather than preserved apart from it. Without further investigation, the site at Lowerwood holds its original purpose close.
