The walls, still roughly 0.8 metres thick and 0.6 metres high where they survive, trace out an approximately rectangular area of around 220 metres by 215 metres. That a field system of this scale should be half-swallowed by bogland is not unusual in Ireland; blanket bog has been advancing over formerly farmed ground since the early medieval period and in some areas much earlier, preserving beneath it the bones of settlements that were quietly abandoned or simply overtaken.

What makes this particular site worth pausing over is that the walls are not alone. Within this network of boundaries lie two enclosures and a hut site, suggesting that the field system at Dromroe was once part of a more complete small settlement, where people lived alongside the land they were dividing and working. Many of the stones in the walls are set at right angles to the wall line, a construction detail that points to deliberate building rather than casual clearance. The rough hill pasture that surrounds them today gives little away, but the ground underfoot holds the outline of a place where someone once decided where one field ended and another began.
