This medieval earthwork is part of a wider archaeological landscape; three fulachta fiadh, ancient cooking sites, can be found approximately 70 to 100 metres to the south and south-southwest of the castle remains.

The main defensive structure consists of a circular area measuring 42 metres north to south and 40 metres east to west. It’s defined by three distinct features: a scarp standing 1.8 metres high, though partially hidden by vegetation; a substantial waterlogged fosse, or defensive ditch, that reaches 9.45 metres in width and 1.8 metres in depth; and an impressive intervening bank that rises over 2 metres high with a sloping top that tilts inward. The bank shows signs of modification in the southwest sector, where it appears to have been adapted to create a walkway with inner and outer banking.

What makes this site particularly interesting is the L-shaped bailey extending from the main circular fortification. At the north-northeast, the wide bank opens out to form this additional defensive area, measuring about 15 metres north to south with an 18-metre return running east to west, all defined by narrower banks on either side. Time and weather have taken their toll on the structure; the external face of the bank has eroded badly in the southeast and southwest sectors, whilst the northern side has been reduced to a scarp with an outer fosse measuring 11.15 metres wide. Dense overgrowth now obscures much of the interior, preserving its mysteries for future archaeological investigation.
