At Clonagh in County Limerick, a hollow-way of this kind cuts across the landscape toward the western entrance of an early Christian ecclesiastical enclosure. A hollow-way is precisely what it sounds like: a sunken trackway, formed gradually as the passage of feet, animals, and carts erodes the path below the level of the surrounding ground. This one runs roughly ten metres wide and is flanked on either side by a low bank of earth and stone, giving it the character of a corridor rather than a simple track.

The road leads directly to the western entrance of an enclosure that contains the remains of Clonagh Church and its associated graveyard. Early Christian ecclesiastical enclosures in Ireland, typically circular or oval in form, were the organising feature of early medieval religious settlements, and the presence of a formal approach road suggests this site was significant enough to warrant a managed route of entry. The precise dating of the trackway remains uncertain, which is not unusual for features of this type; hollow-ways can be difficult to assign to a specific period because they accumulate use over very long spans of time. The route has been recorded and mapped on the revised Ordnance Survey six-inch map, and aerial photographs taken in March 2006 as part of the Archaeological Survey of Ireland provide a useful overhead perspective of the feature in relation to the wider enclosure.

The site sits within a wider complex recorded under the reference LI028-066001, which encompasses the church ruins and graveyard alongside the trackway itself. For anyone wishing to locate it, the revised OS six-inch map is the most reliable guide to the route. The earthen banks that define the hollow-way are low and might not register as significant at first glance; they are the kind of feature that rewards slow walking and a willingness to read the ground rather than the skyline. The approach from the west, following the line of the hollow-way toward the enclosure entrance, gives a reasonable sense of how the site would once have been approached by those who used it regularly.
