Today, walking across the gently sloping, north-facing pasture at Boytonrath, you would find nothing to suggest it was ever there. No earthwork, no raised lip of ground, no shadow in the grass. A field boundary running east to west now cuts straight through where it once sat, bisecting whatever arrangement of ditches or banks may have defined it.

Enclosures of this kind are common enough in the Irish landscape, modest circular or oval features that might represent an early settlement, a stock enclosure, or the boundary of a small farmstead dating anywhere from the prehistoric period through to the early medieval. What makes this one quietly interesting is precisely its invisibility. The mapmakers of the early twentieth century recorded something their predecessors had seen fit to note, and the ground has since swallowed it. Two related features survive nearby, another enclosure approximately 200 metres to the south-west and a ringfort, a type of enclosed farmstead typically dating to the early medieval period, roughly 380 metres to the north-east. Together they suggest this patch of Tipperary pasture was once a more densely settled or managed landscape than its current appearance would imply.
