Measuring approximately 15 metres north to south and 12 metres east to west, the structure is defined by what remains of a stone bank or wall, now reduced to a low, grass and bramble covered rise standing just 30 to 40 centimetres high. The eastern side appears more substantial, with a higher external scarp reaching about a metre in height, which aligns with a natural break in the slope at the eastern edge of the larger oval enclosure that contains it.

The structure’s walls show several breaks and gaps; there’s a low area or rough gap in the middle of the western wall, a break in the northern wall, and rough breaks at both the southwestern and southeastern corners. Within the interior, two low, vegetation covered stony mounds, each measuring 2 to 2.5 metres across, may represent field clearance heaps from agricultural activity. Interestingly, this enclosure doesn’t appear on any edition of the Ordnance Survey 6 inch maps, and whilst its outline is clearly visible from aerial photography, it proves challenging to trace at ground level.

Dating and interpreting this structure remains difficult. It may or may not be contemporary with the outer oval enclosure that surrounds it, and its function remains uncertain. Whilst it could have served as an animal pen, the possibility that these are the ruins of a building or house cannot be ruled out. The site was brought to the attention of the National Monuments Service by Martin Cauley, adding another intriguing piece to the complex archaeological landscape of Donegal.
