On a gently rolling hilltop near Outeragh, a nearly square enclosure measuring roughly 28 metres across has been levelled so thoroughly that it leaves no obvious trace for a casual walker. What remains is a cropmark, the outline of an ancient fosse, or ditch, picked out in lush grass and thistles growing where the disturbed, once-waterlogged earth still holds moisture differently from the surrounding pasture. The fosse itself was between three and four metres wide, suggesting this was once a substantial enclosed space, though what it contained and who built it remain open questions.

The site has its own small archaeological neighbourhood. A large conjoined enclosure sits immediately to the east, associated field banks run nearby, and about 150 metres to the north-east stands a bivallate ringfort, meaning a ringfort defended by two concentric banks and ditches rather than one. That cluster of monuments points to a landscape that was, at some point, meaningfully organised and occupied. By 1982, when a surveyor named Cahill recorded it, the enclosure could still be traced as a low bank and fosse at ground level. Earlier still, an aerial photograph taken on 13 July 1966 shows the area obscured by trees, suggesting the earthwork was at that point partially hidden by woodland. Later aerial photographs from the mid-1990s capture the cropmark clearly, the shape of the enclosure readable from altitude even as it becomes harder to resolve on the ground.

The square form is itself worth noting. Ringforts and enclosures in Ireland are overwhelmingly circular; a rectilinear example sits slightly outside that norm and invites speculation about function or date, though the available evidence does not settle either question. The thistles and greener grass that trace its outline are, in their quiet way, doing the same work an excavation might do, marking where the ground was once cut and shaped by people whose purposes are no longer known.
