At Curraghmulmurry in County Galway, an oval enclosure roughly thirty metres from north to south and twenty metres from east to west once occupied a patch of grassland hemmed in by boggy ground on either side. Today, the only physical hint that anything was ever here is a slight depression running from the north to the north-east, which may represent the ghost of a fosse, the defensive or boundary ditch that would originally have defined the enclosure's edge. Everything else has been levelled, eroded, or simply absorbed back into the land.

The enclosure was recorded on the third edition of the Ordnance Survey six-inch map, published in 1930, which gives some indication of when it was still legible as a feature in the landscape, even if only from a surveyor's careful eye rather than any obvious ground-level remains. Enclosures of this general type, oval or roughly circular earthworks defined by a bank and fosse, are found across Ireland and are associated with a broad range of uses over many centuries, from early medieval settlement and farming to ritual or territorial demarcation. Without excavation it is rarely possible to say which function applied, or when precisely the site was in use. At Curraghmulmurry, the boggy terrain pressing in from east and west would have shaped the character of the place considerably, making it a relatively dry island in an otherwise waterlogged stretch of ground, which may itself explain why someone chose to enclose it.
