The first edition Ordnance Survey six-inch map, produced in 1840, makes no mention of it at all, despite the fact that the earthwork sitting in this County Limerick pasture is substantial enough to be unmissable on the ground. It only appears on the later 1897 twenty-five-inch edition, recorded as a circular earthwork or platform with an external diameter of roughly 26 metres north to south and 25 metres east to west. Whether the earlier surveyors simply overlooked it or considered it unremarkable enough to omit is not recorded.

A rath, to give this type of monument its Irish name, is a roughly circular enclosure defined by an earthen bank and ditch, typically dating to the early medieval period and most likely used as a farmstead or enclosed settlement. The Ballyouragan example sits on a slight north-northeast-facing slope within the demesne lands of Caherass House, which lies about 590 metres to the southwest. When the Archaeological Survey of Ireland inspected the site in 2000, they found a raised, roughly circular platform with an interior diameter of around 23 to 24 metres, defined by a scarped edge, meaning the bank has been cut back to form a steep outer face. Beyond that edge runs an external fosse, the ditch that typically accompanies such earthworks, measuring 6.6 metres wide, though relatively shallow at half a metre deep on the interior side and shallower still on the exterior. About 85 metres to the north lies a separate mound, recorded under its own reference number, which adds a layer of intrigue to the immediate landscape.

The site sits roughly 500 metres northeast of the River Maigue and the townland boundary with Ballynahown, and it remains in agricultural pasture, so access would depend on landowner permission. The interior of the rath is described as dry and clear of overgrowth, which is something of a rarity and makes the form of the earthwork easier to read than many comparable sites. For those who find aerial perspectives useful, the monument shows up clearly on Google Earth orthoimages from both June 2018 and February 2020, which gives a good sense of its shape and scale before visiting. The slight northward tilt of the interior and the clean scarped edge are the details worth looking for once you have your bearings.
