At roughly 37 metres in diameter, the outline is still traceable as a slight scarp, a low earthen step where the ground quietly announces that something deliberate once stood here.

The site sits on a gentle rise in the low-lying grassland around Abbert in north County Galway, the kind of modest elevation that would have made obvious sense to whoever built it. It was originally bivallate, meaning it had two concentric enclosing banks or walls rather than one, a form associated in Ireland with enclosed farmsteads, local seats of authority, or occasionally ceremonial use during the early medieval period. The ring of trees noted on the nineteenth-century Ordnance Survey map suggests the enclosure was still a legible feature in the landscape when surveyors passed through, the trees planted along or near the outer bank, perhaps to mark a boundary or simply because the earthwork provided a convenient edge. Those trees, and the banks themselves, are now gone.

Visitors looking for drama will find none. What remains is a slight rise in an otherwise level field, perceptible mainly because you are looking for it. The value here is less in what survives than in what the first edition map records: a complete, tree-ringed double enclosure that, within a century or two of being documented, had almost entirely vanished into the ground.
