Measuring 22 metres across, this barely visible feature sits atop a limestone ridge, its perimeter marked only by a gentle rise in the ground, dotted with mossy tussocks and the occasional stone peeking through the grass. The enclosure occupies a plateau that forms a natural spine of level ground running north to south through the centre of the hillfort, with a 6-metre-wide opening facing north-northeast that likely served as an entrance.

What makes this site particularly fascinating is its relationship to the surrounding archaeological features. Directly adjoining the enclosure on its eastern side are the remains of what appears to be a circular house, suggesting this wasn't just a ceremonial space but part of a living, breathing settlement. Just 13.5 metres to the north stands a larger circular enclosure containing a cairn that marks the highest point of the ridge; a placement that was surely no accident in a culture that often imbued high places with spiritual significance.

Though the enclosure is hardly noticeable from ground level today, requiring a trained eye to spot its outline amongst the pasture, it forms part of a complex archaeological landscape that reveals how our ancestors organised their hilltop settlements. The limestone ridge provided both defensive advantages and commanding views across the Donegal landscape, whilst the careful arrangement of structures within the hillfort hints at a sophisticated understanding of space, hierarchy, and perhaps ritual practice in Iron Age Ireland.
