The structure, which likely began as a rectangular enclosure before being extended southward, measures approximately 19.55 metres east to west and 16.1 metres at its widest point north to south. This ancient site, surrounded by rough terrain but situated in relatively good pasture land, offers a glimpse into Ireland's long tradition of religious pilgrimage and penance.

Within the stone walls stand three distinctive penitential cairns, each topped with significant stone slabs that bear witness to centuries of devotional practice. The first cairn forms a horseshoe shape measuring 3.85 by 4.5 metres and rising to 1.46 metres in height, with a central slab displaying two simple crosses on its northwestern face. The second cairn, similar in height but slightly smaller at 4.35 by 3.4 metres, features a slab with an intriguing geometric design; rectangular grooved divisions run along each edge of its northern face, suggesting careful craftsmanship and symbolic meaning.

The third and largest cairn stretches 4.9 by 3.6 metres and stands 1.2 metres tall, crowned by an uninscribed slab that some observers suggest has a vaguely cross-shaped elevation, though this may be more suggestive than deliberate. These cairns would have served as stations for pilgrims undertaking religious journeys, providing physical markers for prayer, contemplation, and acts of penance. The site represents an important example of Ireland's penitential landscape, where religious devotion was literally built into the countryside through carefully constructed monuments that guided the faithful through their spiritual exercises.
