The monument sits in rough pasture about 300 metres west of the Bungosteen River, its weathered stones emerging from a long, grassy mound that stretches nearly 30 metres in length. Though a trackway has damaged the western end of the structure, and centuries of weather have taken their toll, the tomb’s essential form remains visible, telling a story of Neolithic construction techniques and ritual practices.

The monument consists of two distinct sections: a gallery chamber opening from what was once a ceremonial court, and the ruins of a separate chamber positioned about 7.5 metres away at the eastern end. The main gallery preserves several key architectural features, including well-matched entrance jambs standing 0.7 to 1 metre high, topped by a substantial lintel stone measuring over 2 metres long. Behind these, pairs of opposing orthostats create distinct chambers within the gallery, with massive corbel stones, some reaching 1.7 metres in height, still resting against the sides. The court area, though partially collapsed, retains four recognisable courtstones that would have formed part of the ceremonial forecourt where rituals likely took place before bodies were interred in the tomb chambers.

Archaeological surveys suggest two possible original designs for this complex structure: either both chambers opened onto opposite ends of a large central court, or the eastern chamber served as a subsidiary structure attached to a full terminal court. Both architectural styles are known from other Neolithic monuments in this part of Donegal, dating to roughly 3500-3000 BCE. Historical accounts from as early as 1847 describe the monument in much the same condition as today, suggesting its current state of preservation has remained relatively stable for at least 175 years. Despite the passage of millennia, enough of the structure survives to appreciate the considerable engineering skills of its builders, who transported and erected these massive stones without modern machinery, creating a lasting memorial to their dead.
