Ringforts, known in Irish as raths, were typically enclosed farmsteads of the early medieval period, defined by one or more earthen banks and a surrounding ditch. This one is larger than most, and its shape is unusual: not the standard circle but something closer to a sub-rectangle, running roughly 53 metres on its longer axis and 34 metres across.

When the Ordnance Survey mapped this part of Limerick in 1840, the fort was recorded on their six-inch map under the name 'Logalean Fort', depicted as a large, roughly oval enclosure still legible in the landscape. By the time the more detailed 25-inch survey was carried out in 1897, the picture had already worsened. The western half of the monument was noted as enclosed by a bank that had been reduced to little more than a scarp along its northern arc, while the south-eastern portion had been levelled entirely. That pattern of gradual loss continued into the twentieth century, and the remains visible today consist of a degraded earthen bank and an external fosse, the term for the ditch that typically ran outside the bank of such enclosures, both still traceable on the ground and visible on aerial imagery recorded as recently as February 2018.

The site sits on private farmland immediately east of the Clareville Water Treatment Plant, with the Shannon running about 120 metres to the north. There is no formal public access, and the monument is not signposted. The clearest sense of its surviving shape comes from overhead, through satellite imagery, where the sub-rectangular outline of the fosse and bank can still be read against the pasture. For anyone passing through the area with an interest in early medieval settlement, it is worth knowing that what looks like a slight rise or a grassy irregularity in an otherwise unremarkable field was once, in all likelihood, a working farmstead at the edge of one of Ireland's great rivers.
