Occupying most of the south-western quadrant and measuring roughly 16 metres north to south and 12 metres east to west, the steep-sided depression runs right to the edge of the fosse, the defensive ditch that encircles the site. Whether it is the result of deliberate excavation, later disturbance, or something more ancient is not recorded, but it gives the interior an unsettled quality that sets this rath apart from more straightforward examples.

The ringfort sits on top of a west-facing slope at Railstown, in County Tipperary, and its overall plan is nearly circular, measuring 31 metres north-west to south-east and 30 metres north-east to south-west. A rath, in general terms, is an early medieval farmstead, typically dating from roughly 500 to 1000 AD, enclosed by one or more earthen banks and ditches. Here the enclosing scarp is still substantial in places, running to 2.2 metres in height and 5 metres in width, though the outer bank has fared less well; it survives reasonably intact on the western and south-eastern arcs but has been levelled entirely along the northern side. The external fosse, 8 metres wide, is now largely obscured by trees leaning inward from both edges. Two causeways cross the ditch: the main entrance, about 5 to 6 metres wide, lies to the east-south-east beside a natural depression in the ground outside the bank, while a narrower secondary crossing of around 4 metres sits to the west, where there is also a slight breach in the inner scarp. A second ringfort lies approximately 265 metres to the south-west, suggesting this was once a settled and organised landscape rather than an isolated farmstead.

The site sits in pasture, so the earthworks remain largely legible at ground level. The surviving scarp on the western arc gives the clearest sense of the original enclosure's scale, while the tree-lined fosse, though overgrown, can still be traced by its shadow in low, raking light.
