This ancient enclosure, measuring roughly 20 metres across, presents itself as a nearly circular earthwork whose western portion has been truncated by a modern road. The surviving eastern section still boasts an impressive earthen bank standing up to 1.25 metres high, whilst the particularly lush vegetation growing around its exterior hints at what may be the remains of a silted defensive ditch, or fosse, that once provided additional protection to this sacred space.

The interior of the enclosure holds its own mysteries, with a small circular mound occupying the northwestern section and a noticeable hollow depression running along the eastern bank. These features suggest various phases of use and modification over the centuries, typical of early Irish ecclesiastical sites that often served multiple functions within their communities. The presence of St. Patrick's holy well just 100 metres to the west strengthens the religious significance of this location, indicating it was likely part of a broader sacred landscape that served the spiritual needs of the local population.

Though now surrounded by cultivated farmland, this site represents an important piece of Donegal's ecclesiastical heritage. The combination of the enclosure, its internal features, and the nearby holy well paints a picture of a once vibrant religious centre that would have drawn pilgrims and local worshippers alike. Its position overlooking Lough Foyle would have provided both practical advantages and symbolic significance, offering views across the water whilst maintaining a connection to the fertile lands that sustained the community.
