It is the kind of feature that most people pass without registering, yet it marks something considerably older than the village beside it: a rath, or ringfort, a type of enclosed farmstead typically built during the early medieval period, roughly between the fifth and twelfth centuries. Thousands of these earthworks survive across Ireland, but each one occupies a specific place in the landscape, and this one sits precisely on the townland boundary between Ballyanrahan and Attyflin, suggesting it may have functioned as a marker in the land as much as a domestic enclosure.

The monument was recorded on the Ordnance Survey six-inch map of 1840, where it appears as a circular area defined by a bank, with trees planted inside. By the time the more detailed twenty-five-inch OS map was produced in 1897, surveyors were able to record it with greater precision: a roughly circular raised area with an internal diameter of approximately 28 metres and an external diameter of approximately 45 metres. A bank encloses the site from the south, around through the west, and up to the north, where a field boundary takes over the circuit. An external fosse, the term for a ditch dug around the outside of an earthwork, runs from the south-west through the west to the north, meeting a field boundary in the south. The combination of bank and fosse is characteristic of a well-defined rath, and the dimensions place it in a fairly typical size range for the type. The record was compiled by Martin Fitzpatrick and uploaded in June 2020.

The site sits in pasture roughly 150 metres north of Patrickswell's Main Street, which makes it physically close and yet not obviously accessible from a public road. A Google Earth image taken in February 2020 shows the tree-covered outline still clearly legible from above, though field boundaries now cut across it at the south and east. If you are approaching on foot, the tree canopy is the most useful visual guide, rising slightly above the surrounding grassland. The earthworks themselves are largely intact beneath that canopy, though the southern and eastern edges have been clipped by later field divisions. It is the kind of site that rewards patience and a decent map rather than a spontaneous detour.
