What looks at first like an irregular patch of raised ground turns out to be a roughly oval enclosure, measuring approximately 40 metres northeast to southwest and 32 metres northwest to southeast, its edges defined by a scarp, that is, a subtle but distinct drop in the ground level marking the boundary of the enclosed area. A field boundary running east to west cuts across its southern side, a reminder of how later agricultural use has quietly rearranged older landscapes without entirely erasing them.

The earliest cartographic record of the site appears on the Ordnance Survey six-inch map of 1840, where it is annotated as Knockeenacartan and depicted as a circular enclosure. By the time the 25-inch edition was surveyed in 1897, the shape had been recorded in more detail as the raised oval form that survives today. Enclosures of this kind, broadly circular or oval earthworks defined by a bank or scarp, are among the most common monument types in the Irish countryside, and they occur across a wide range of periods. Their functions varied considerably, from settlement and farming enclosures to ritual or boundary uses, and without excavation the purpose of any individual example remains uncertain. A second enclosure, catalogued separately, lies roughly 200 metres to the southwest, suggesting this part of Curraghturk preserves a small cluster of related features.

The site sits in wet pasture at the edge of a conifer plantation, about 60 metres south of a stream that marks the townland boundary with Ballylanders, so underfoot conditions can be soft, particularly in winter and early spring. The enclosure is visible on Google Earth satellite imagery, which can be a useful way to orientate yourself before visiting, since the scarp that defines it is subtle at ground level and easier to read from above. The surrounding land is agricultural, so access would require landowner permission. Its record in the national monuments database was compiled by Martin Fitzpatrick and uploaded in October 2021.
