It is the kind of thing that happens when the past becomes inconvenient, and it has been happening here for centuries, worked over quietly by ploughs and grazing animals until what was once a substantial boundary is now barely a ripple in the ground.

The enclosure measures 135 metres across in both directions, making it a considerable structure, roughly circular and sizeable enough to have enclosed a small settlement or a significant agricultural complex. An enclosure of this type typically consists of an earthen bank, sometimes accompanied by an outer ditch, that would once have defined and defended a domestic or ecclesiastical space. Here, no external ditch was found, and the bank itself survives to only around 30 centimetres above the interior ground surface on average, though the eastern and southern stretches fare slightly better, reaching 40 centimetres in external height and up to 10 metres in width. The site sits approximately 50 metres north of Annagh church, a proximity that may or may not be coincidental, and the sea lies roughly 400 metres further north again, close enough that salt air and coastal weather have had a hand in whatever erosion the farming has not managed.

What a visitor finds today is a landscape of grazing fields divided by a track, with low grassy banks that require some attention to read. The bank is most legible on the eastern and southern arcs, where the ground swells just enough to suggest the original circuit. The church to the south provides a useful point of orientation, and the whole site rewards the kind of slow, unhurried looking that most people no longer bother with.
