Set in level grassland on the former grounds of Castletaylor Demesne in County Galway, this oval stone enclosure is associated with a children's burial ground, a detail that shifts the whole atmosphere of the place. Such burial grounds, known in Irish as cillíní, were used for unbaptised infants and others considered ineligible for consecrated ground. Their presence beside ancient enclosures is not uncommon in Ireland, where the perceived sanctity of old boundaries made them an instinctive choice for marginal burials across many centuries.

The enclosure itself is a cashel, meaning a ringfort built from stone rather than earth and timber. This one measures roughly 42 metres north to south and 32 metres east to west, an oval rather than a true circle. It is very poorly preserved. On the western side, a low spread of rubble retains intermittent traces of what was once an outer wall-face; elsewhere, the boundary has collapsed into little more than a degraded scarp, a gentle slope in the ground where a wall once stood. Inside the western portion, a low foundation line of boulders and rubble runs east to west. Its purpose is uncertain, though it may represent an internal division of the enclosed space, perhaps separating one functional area from another, as is occasionally seen in similar enclosures elsewhere in the country.

Castletaylor Demesne provides the wider setting, a reminder that many such ancient features survived not despite later estate ownership but because of it, absorbed into ornamental or agricultural land and left largely undisturbed. Here, the cashel endures as an irregular softening of the ground, legible mainly to someone who already knows what they are looking at.
