The castle’s builders chose this spot wisely; the shallow waters here, broken by rocky outcrops and low cataracts, create a natural ford that would have been invaluable for controlling movement through the valley. Whilst the 1838 Ordnance Survey map shows it as a polygonal enclosure measuring roughly 30 to 35 metres east to west, the castle had vanished from maps by 1913, leaving only these enigmatic ruins to tell its story.

Today, visitors will find the ghost of a rectangular building, its outline traced by grass-covered stone banks that once formed sturdy walls. These collapsed ramparts, now standing between 0.6 and 1.7 metres high, define a structure that originally measured 14.4 metres north to south and 8.5 metres across. The walls have slumped inward over the centuries, creating an irregular interior space with a slightly sunken appearance. A three-metre gap in the eastern wall likely marks where the main entrance once stood, though no intact masonry remains visible beneath the covering of sod and vegetation.

The castle appears to have been more than just a solitary tower; archaeological evidence suggests it formed part of a larger complex. Two wall footings extend westward from the building’s corners, possibly the remains of an adjoining room or ancillary structure. Just to the southwest, the faint outline of a square building can still be traced, whilst scattered wall footings to the north hint at what may have been a bawn, a defensive courtyard that would have enclosed the castle proper. Between the main structure and the low ridge defining the valley’s western edge lies a strip of boggy ground, 40 to 50 metres wide, that would have provided an additional natural defence against attack from that direction.
