The bulk of the monument falls within Co. Wexford, but its northern edge bleeds across into Co. Wicklow, giving it a dual identity that mirrors something stranger still about the structure itself: a ring of earth and stone set directly in the course of a stream.

The enclosure measures around twenty metres in diameter, defined by an earthen bank between two and four metres wide and rising to between one and a half and two metres in height. The inner face of that bank is lined with stone cladding, a detail that suggests deliberate construction rather than a simple field boundary thrown up in haste. What makes the layout particularly curious is the water management built into it. A leat, which is an artificial channel cut to direct flowing water, once breached the bank at the north-east, ran along the inner edge of the bank at the north and west, and exited again at the south-west. The leat is now dry, but its course is still legible in the landscape, tracing the interior of the enclosure like a moat in miniature. The name Toberpatrick, from the Irish tobar Phádraig, meaning the well of Patrick, suggests a long association between this place and water, though whether the enclosure itself was connected to any devotional or functional use tied to that name remains unclear. The site now sits in rough pasture, unremarkable to a passing eye, the old watercourse quiet and the stone-faced bank slowly softening back into the ground.
