Sitting among rough pastureland and outcrops of bare limestone at Ballyinsheen Beg, the structure is a cashel, a type of early medieval ringfort built from dry-stone rather than an earthen bank. The revetment, the outer face of carefully laid stone that retains the raised interior platform, survives to between one and nearly two metres in height, with six or seven courses still visibly intact. For a site sitting quietly in an ordinary field, that degree of preservation is quietly remarkable.

The enclosure is almost circular, measuring 24 metres north to south and 23 metres east to west, and its most revealing detail is a gap of about one and a half metres on the west-south-west side. Just outside that opening, a short length of collapsed wall extends outward for around six metres, aligned in the same direction, which suggests the original entrance was approached along a defined pathway or causeway rather than simply breached through open ground. Inside, the platform is uneven, and a grass-covered wall running roughly east-north-east to west-south-west across the northern part of the interior hints at internal subdivision or later use. The cashel does not sit in isolation either. Collapsed earth and stone field boundaries run parallel to the outer wall at a distance of roughly five and a half metres, suggesting that the enclosure was once embedded within a managed agricultural landscape. That wider field system around it has been identified as multiperiod, meaning it accumulated and changed across several distinct eras of human activity. The whole site was already considered significant enough to be marked on the Ordnance Survey six-inch maps of both 1842 and 1920. A hut site lies approximately sixteen metres to the west, adding another layer to what was evidently a cluster of early activity in this corner of Clare.
