The ringfort at Ballinvreena, a roughly circular raised enclosure in the townland of the same name, has long been recorded on maps not as a rath but as a mote, the term used for the earthen mound at the centre of a Norman motte-and-bailey castle. The Irish place name, Baile an Bhruidne, adds another layer entirely, suggesting an association with a bruíon, a hostel or feasting hall from early Irish literature. Whether the earthwork itself prompted that name, or whether it simply absorbed local legend over time, is not something the ground easily gives up.

When the Ordnance Survey recorded it in 1840, they noted it as one of three forts in the townland, describing this particular one as sitting near its centre. The antiquarian Thomas Johnson Westropp examined it in the early twentieth century and measured it with some care: a flat top roughly 26.5 metres across, rising about 7.3 metres at its highest northern side and dropping to around 2 metres at the south where the surrounding slope takes over. He noted slight traces of a rampart to the south, a fosse, that is a defensive ditch, about 2.7 metres wide to the west, and an outer ring, largely levelled by his time but still detectable at around 3.6 metres wide. Westropp also recorded that a fair was held in the vicinity of the mound, and the Ballinvreena Fair Green still sits roughly 135 metres to the west, a reminder that this elevated earthwork once had a social life as well as a military or ceremonial one. A standing stone lies about 200 metres to the south-southwest, hinting that the immediate landscape held significance across several periods.

The site sits in ordinary agricultural pasture, and modern satellite imagery shows the circular tree-lined bank and the outer fosse still legible from certain angles, particularly from the southeast and northwest. There is no formal access or visitor infrastructure, so anyone approaching should do so with permission from the landowner and with an eye for the gentle but distinct rise of the ground. The profile of the mound is most clearly appreciated from the lower ground to the north, where the full 7-metre height is most apparent, and where the distinction between a natural hill and a deliberately shaped enclosure becomes harder to dismiss.
