What makes it worth a second look is its basic composition: it is a cashel, a ringfort built not from an earthen bank but from a drystone wall, the kind of dry-laid stonework that requires no mortar and yet, when well constructed, can endure for centuries in recognisable form. This one, roughly 35 metres across, is in fair condition, which is more than can be said for many of its kind.

Ringforts of this type were the standard unit of rural settlement in early medieval Ireland, typically enclosing a farmstead and its associated buildings. The cashel form is especially common in areas where stone was more readily available than good building timber or compact soil for earthwork. Here, the enclosing wall is still legible, though time and agriculture have left their marks. A shallow external fosse, a defensive ditch, survives in traces on the southern side. On the western side, a later field wall has been built directly over the enclosing element, absorbing the ancient boundary into the working landscape in the way that happened across rural Ireland as successive generations simply made use of whatever material lay to hand. A gap in the northeast looks to be a modern intrusion rather than an original entrance.
