A ringfort, sometimes called a rath, is a roughly circular enclosure defined by one or more banks and ditches, typically built during the early medieval period as a defended farmstead for a single family or small community. What makes this one in Tooraleagan worth a closer look is not dramatic height or preserved stonework, but a subtler quality: the way it sits at the edge of a townland boundary, beside a river with the evocative name Ahaphuca, within a loose cluster of related monuments that suggest a landscape once considerably more populated than it appears today.

The site lies 120 metres east of the Ahaphuca River, which itself marks the boundary between Tooraleagan and the townland of Tulla. It was already recorded on the Ordnance Survey 25-inch map of 1897, depicted there as a raised, sub-rectangular area roughly 20 metres north to south and 24 metres east to west, defined by a scarp with an external fosse, a narrow ditch, and an outer bank running from the south-east around to the north-west. When the site was surveyed in 1978, it was described as a double-banked and ditched ringfort approximately 22 metres in diameter, with a ditch two metres wide and an outer bank half a metre high surviving on the western side. A dyke running east to west has truncated the northern edge, and at the north-west a rectangular area roughly six by ten metres, enclosed by low banks, may represent the remains of a structure, perhaps an outbuilding or small enclosure associated with the original settlement. A standing stone lies 300 metres to the south-east and a separate enclosure 350 metres to the east, hinting that this part of the Limerick countryside was once organised around a cluster of related features rather than any single monument.

The site sits in working pasture, so access is a matter of courtesy rather than formality; there is no public path to the monument itself. The outline of the sub-rectangular enclosure is visible on satellite imagery, where it is clipped on the north by a watercourse and on the east by a farm track running north to south. Visiting in late autumn or winter, when low vegetation makes earthworks easier to read in raking light, gives the best chance of appreciating the surviving scarp and outer bank. The nearby standing stone to the south-east is worth locating as a separate point of reference for understanding how these monuments relate to one another across the wider landscape.
