It is only about 76 centimetres above the surrounding field, and much of its original form has been worn away, yet the basic geometry of this early medieval ringfort, a rath, persists. A rath is a type of enclosure common across Ireland, typically consisting of a raised earthen platform ringed by a bank and external ditch, and used as a farmstead and place of shelter during the early medieval period. This one is modest in scale, measuring roughly 36 metres across overall, and the entrance that once allowed people and livestock in and out has long since disappeared.

The site was recorded by O'Kelly in 1942 to 1943, and published in the following year's survey notes. At that point, the monument had already been levelled on its south-western and north-eastern sides, damage almost certainly caused by tillage or land improvement works that would have been ongoing across Irish farmland throughout the nineteenth and early twentieth centuries. The surrounding marsh bordering the Morning Star river, which O'Kelly described as extensive, would once have made this a well-chosen location; ringforts sited near wetlands often benefited from the natural defensive qualities of waterlogged ground, while still maintaining access to fresh water and pasture. The fosse, or external ditch, that originally encircled the platform is another indicator of a desire for defensible space, even if the enclosure itself was primarily agricultural in function.

The site lies within the Smallcounty barony of County Limerick, in the townland of Crean. Because so much of the earthwork has been reduced by ploughing, what a visitor sees today is less a dramatic raised platform than a faint but perceptible swelling in the ground, best appreciated in low winter light when shadows pick out slight changes in relief. The proximity to the marsh and the river remains one of the more evocative aspects of the setting, offering a sense of how the original inhabitants might have read and used the surrounding terrain.
