Stone Monuments
Within the grounds of Ballinrobe Demesne in County Mayo, an incomplete ring of ancient stones sits among natural rock outcrops, easy to overlook and difficult to date with certainty.
Stone circles, broadly speaking, are prehistoric monuments in which upright stones, known as orthostats, are arranged in a roughly circular plan. Their purposes remain debated, but alignments with solar or lunar events are common, and this circle's orientation running from south-west to north-east hints at exactly that kind of deliberate placement by its builders.
Eight stones survive, though the circle as originally constructed may have held more. The orthostats vary considerably in size, ranging from 0.4 metres to 1.8 metres in length, 0.2 to 0.69 metres in thickness, and between 0.3 and 1 metre in height above ground. That variation in height is not unusual in Irish stone circles, where the tallest stone often marks a significant point in the ring's geometry, sometimes the entrance or the axis of alignment. The setting among natural rock outcrops adds a layer of ambiguity; it is not always straightforward to distinguish placed prehistoric stones from the surrounding geology, which may partly explain why this circle has attracted relatively little attention.
