It is a quietly eccentric piece of nomenclature that suggests the place was once well known for something as domestic and unheroic as a fruiting shrub, rather than any martial or ceremonial distinction. That name, recorded by P.W. Joyce in 1913, appears on the 1840 edition of the Ordnance Survey six-inch map, where the site is marked as a circular fort. By the time the 25-inch map was surveyed in 1897, the same enclosure was depicted as a roughly heptagonal shape, an apparent contradiction that likely reflects the difficulty of mapping a scrub-covered earthwork from the ground rather than any genuine change to the structure.

When archaeologists from the Archaeological Survey of Ireland inspected the site in 2001, they found a roughly circular interior with an internal diameter of around 30 metres, enclosed by a flat-topped bank of earth and stone measuring some 5.7 metres wide and 0.6 metres high, with an entrance gap of 8 metres on the eastern side. A cashel, for those unfamiliar with the term, is a ringfort defined by a stone wall rather than an earthen bank, and the surveyors noted that the bank here is particularly rocky and may represent the collapsed remains of just such a wall. No fosse, the external ditch that typically accompanies earthen ringforts, was identified, which lends some weight to the idea that the original boundary was stone rather than earthwork. A second enclosure lies roughly 200 metres to the southwest, suggesting this part of Garranroe was once a more populated early medieval landscape than its present rural quiet implies.

The site sits on an elevated, slightly southwest-facing slope, just ten metres north of the townland boundary with Fanningstown. The elevated position gives wide views across the surrounding countryside, and it is easy to see why someone chose this particular spot. Access is through farmland, so the usual courtesies apply before approaching. Any visitor should be prepared for dense scrub and mature woodland covering the interior and the bank, as confirmed by aerial imagery from 2018 and 2020. The earthworks are legible but not immediately obvious from a distance, and the tree cover means the heptagonal outline recorded on the Victorian map is now far less apparent than the rougher, more organic shape that the woodland has imposed on the site.
