The rath at Mountpotter does the opposite. It sits in low-lying grassland, poorly preserved and easy to overlook, its outline only legible to someone actively looking for it. What survives is a subcircular enclosure measuring roughly 36.5 metres east to west and 29.5 metres north to south, defined partly by a bank and partly by a scarp, a slight drop in ground level, running from the north-east around to the east. A gap on the south-eastern side may be original, possibly the entrance through which people and livestock passed in and out over a thousand years ago.

A rath is an early medieval farmstead enclosure, typically built between the sixth and tenth centuries, in which an earthen bank and sometimes a ditch defined a protected living space for a single family and their animals. Tens of thousands were built across Ireland, and they remain the most common field monument in the country, though many have been reduced by centuries of ploughing, drainage work, and land clearance. The Mountpotter example fits that broader pattern of attrition. Its subcircular shape is typical of the form, and the surviving scarp on the north-eastern to eastern arc suggests that the original bank was more substantial before the surrounding grassland levelled it out over time. The possible original entrance at the south-east is a detail worth noting; many raths were oriented to face the rising sun or to open towards the most-used approach to the farmstead.
