Near the northern shore of Lough Cutra in County Galway, a circular enclosure roughly 27 metres in diameter was recorded on the third edition of the Ordnance Survey six-inch map, published in 1921. That map showed not just the outline of the enclosure but a single tree at its centre, the kind of detail that suggests something was still legible in the landscape at the time of surveying. Today, nothing visible remains.

Circular enclosures of this type are a common feature of the Irish countryside, typically interpreted as the remains of ringforts, the enclosed farmsteads that were built and occupied from the early medieval period onwards. A diameter of 27 metres would place this example at a modest but unremarkable size for such a structure. What makes the Carrowgarriff site quietly interesting is the contrast between its recorded appearance and its current state. The 1921 map captures a moment when the enclosure still had enough presence to be worth marking, complete with its central tree, a detail that sometimes indicates a site that had been left deliberately untouched within farmed land. At some point between that survey and now, whatever earthwork or stony boundary defined it dissolved back into the grassland and rock outcrop that surrounds it.
