This grass-covered mound rises just 30 centimetres above the surrounding wetland, measuring approximately 14 metres across its interior. Though a field boundary has cut through its northern side, giving it a D-shaped appearance today, the earthwork was almost certainly circular when first constructed.

The site occupies an intriguing position in the landscape; whilst the immediate surroundings are level and waterlogged, steep ground rises dramatically to the north, creating a natural amphitheatre effect. This placement, combined with the local folklore surrounding its purpose, suggests the mound held some significance for the community, whether as a genuine burial site, a place of religious observance, or perhaps serving an entirely different function lost to time.

The exact age and original purpose of this earthwork remain uncertain, though its presence in the Archaeological Survey of County Donegal confirms its historical importance. Similar raised platforms across Ireland have been variously interpreted as prehistoric burial monuments, medieval assembly places, or even post-medieval religious sites; the persistent local tradition of calling this one a ‘Calvary’ might hint at its use during the Christian period, possibly as a site for outdoor religious gatherings or processions.
