What makes the site at Kilshanvy quietly unusual is that it consists of two enclosures joined together, a configuration sometimes called a conjoined rath, with a trackway running between them as if to formalise the connection. That internal path suggests the two spaces were not simply adjacent by accident but functioned in some deliberate relationship, perhaps separating different activities, different livestock, or different members of a household across the same settlement.

The northern enclosure is roughly subcircular, measuring around 31 metres east to west and 27 metres north to south, and is defined partly by an earthen bank and partly by a quarried-out scarp along its north-eastern to south-eastern edge, where natural or worked ground levels drop away to form the boundary. The southern enclosure is more irregular in shape, stretching approximately 30 metres, and uses a similar combination of bank and scarp. Inside the southern enclosure there is a souterrain, an underground stone-lined passage or chamber of the kind commonly associated with early medieval settlement in Ireland, likely used for storage or as a place of refuge. The site sits in low-lying grassland and is poorly preserved, meaning the banks and scarps have been reduced considerably over the centuries, but enough survives to read the layout of the two enclosures and the track between them.
