Most raths, the circular earthen enclosures built across Ireland during the early medieval period, roughly between the fifth and twelfth centuries, read from a distance as a simple ring, a bank, a ditch, a defined space within. This one in County Limerick holds a more intricate arrangement inside its perimeter, one that only becomes apparent on closer inspection or, as surveyors have found, when viewed from directly above.

The site sits in elevated pasture on a slight east-facing slope in the townland of Briska More, around 133 metres south of the boundary with Elmpark Demesne and 190 metres east of the boundary with Briska Beg. The enclosing bank, which runs from north-north-east to south-south-west, measures roughly 35 metres across at its widest and retains well-preserved stone revetting, a facing of stone set against the earthen core to hold its shape. That bank has been incorporated into a field boundary over time, which is a common fate for these structures and explains why so many survive only partially. The interior, though, is where this rath distinguishes itself. A bank running roughly east to west for 28 metres divides the space internally and connects at its eastern end to a second bank of equal length. A shorter, slightly curved bank sits in the north-west corner. These internal divisions, documented by Fiona Rooney and uploaded to the record in June 2020, are clearly visible on aerial imagery captured in November 2019, where the undulating ground resolves into a legible pattern of subdivisions.

The site is in working farmland, with a modern farmyard immediately to the south-west, so access would require landowner permission. There is no formal public access or signage. The aerial images logged with the survey record are a useful starting point for understanding the layout before visiting, since ground level does not always reveal what the overhead view makes plain. The internal banks are low, none exceeding 0.4 metres in height, so a visit in winter or early spring, when vegetation is reduced, gives the best chance of reading the ground surface clearly.
