This oval platform measures 32 metres north to south and 41 metres east to west, surrounded by a fosse that’s 1.5 metres wide but only 15 centimetres deep; a rather shallow defensive ditch by most standards. An outer earthen bank rises up to a metre in height around most of the perimeter, though it diminishes to just a few centimetres along the northern sector. Interestingly, there’s no clear evidence that an inner bank ever existed, which would have been typical for many defensive enclosures of this type.

Two gaps pierce the enclosure’s defences: one to the northwest spans 4 metres wide, whilst another to the east measures 3.6 metres across. Whether these served as original entrances or resulted from later damage remains uncertain. Along the east-northeast sector, faint traces suggest there may have been an additional outer fosse, though time has rendered these features barely discernible. The interior space remains level but marshy, perhaps explaining why this particular spot was chosen for an enclosure rather than settlement.

The site commands an impressive view southward towards Donegal Bay, a strategic position that would have allowed its occupants to monitor maritime traffic and approaching visitors. This elevated vantage point, combined with its defensive features, suggests the enclosure served multiple purposes; possibly as a fortified farmstead, a livestock enclosure, or a gathering place for the local community. The Archaeological Survey of County Donegal first documented these remains in 1983, preserving details of this enigmatic earthwork that might otherwise have been lost to memory.
