What makes them worth pausing over is not their height, which ranges between just fifteen and twenty-five centimetres, but their arrangement: four conjoined rectangular or sub-rectangular enclosures, their banks measuring up to 3.7 metres across at the base, laid out with enough regularity to suggest deliberate planning rather than natural accident. Some of the surrounding earthworks dissolve into less recognisable patterns, but this cluster, sitting roughly thirty metres east of the local graveyard, holds its shape.

The enclosures lie within the field that contains Railstown church and graveyard, and they are thought to be connected to a deserted settlement known as Railstown or Kilbragh, the earthworks of which survive about two hundred metres to the southwest. Deserted settlements of this kind, sometimes called deserted medieval villages, were once ordinary communities that shrank, shifted, or simply vanished, leaving behind only faint traces in the soil and grass. The precise sequence of enclosures here, three running roughly south to north and a fourth running east to west and joining the latter two, may reflect boundaries, yards, or building plots from that lost community, though nothing in the current evidence pins down a firm date or function. The landscape around them is gently undulating pasture, and the rise on which the earthworks sit gives the site a mild prominence that may itself have influenced where people chose to settle or organise their land.
