Roughly oval in shape and measuring around 28 metres north to south and 17 metres east to west, it survives in very poor condition, its outline traced only by a low bank running from the south-west, around to the north, and back down to the south-east. Without knowing what to look for, a person could walk across it without registering anything older than the field itself.

Enclosures of this type, defined by an earthen bank and sometimes a fosse or ditch, are among the most common but least understood monument types in the Irish landscape. They could have served as farmsteads, livestock enclosures, or ceremonial spaces, depending on their period and context, and without excavation it is rarely possible to say which. At Loughbown, a gap roughly four metres wide at the northern side of the bank may represent an original entrance. Along the inner face of the bank, a depression runs from the north around to the south-east, possibly the ghost of an internal ditch or drainage channel. Outside the enclosure to the east and south, irregular mounds and hollows suggest that something further once occupied the surrounding ground, though what precisely remains unclear.

The site is very poorly preserved, and a visitor would need patience and a reasonable eye for subtle earthworks to make much of it on the ground. The low bank, the possible entrance gap, and the disturbed ground outside the eastern and southern sides are the key features to look for, best read on a dry day when low-angle light picks out slight changes in the surface of the grass.
