The one at Boley in County Wicklow does none of these things. It exists primarily as an absence, a feature recorded on a first-edition Ordnance Survey map as an oval enclosure measuring roughly 35 metres east to west and 25 metres north to south, but leaving no visible trace on the ground today. The improved pasture that covers the site has long since smoothed away whatever physical boundary once defined it.

The enclosure sat on a small level platform, approximately 25 metres in diameter, on a gentle south-west facing slope, with a more pronounced drop in the ground just below. Enclosures of this kind are a common feature of the Irish countryside, ranging from prehistoric agricultural boundaries to early medieval ringforts, which were enclosed farmsteads typically defined by an earthen bank and ditch. Without further investigation it is not possible to say which category this one belongs to, but its position on a sheltered, south-west facing slope overlooking a steeper gradient is consistent with the practical logic of early settlement, favouring ground that caught the sun and gave a clear view of the terrain below. Whatever stood or grew within its boundary, the land has since been regularised into the undifferentiated green of modern farming.
