This ancient earthwork, measuring 37 metres across its interior, forms an almost perfect circle enclosed by an impressive earthen bank that rises up to 3 metres in height. A single 3.7-metre gap on the western side marks what was likely the original entrance, where residents and visitors would have passed through centuries ago.

The ringfort’s defences extend beyond the main bank, with both a fosse (defensive ditch) and an outer bank adding extra layers of protection to the settlement. These multiple defensive features suggest this was once home to a family of some local importance, as ringforts with such elaborate earthworks typically belonged to more prosperous farming communities. Today, the site sits within land undergoing reclamation, its ancient banks still clearly visible against the changing landscape.

Local folklore adds an intriguing dimension to the site, with traditions speaking of a cave somewhere within the ringfort’s interior. Despite these stories being passed down through generations, no physical evidence of such a feature has been found during archaeological surveys. This blend of tangible archaeology and intangible heritage makes the Kilrean Upper ringfort a fascinating example of how Ireland’s ancient sites continue to capture the imagination, even as they yield their secrets to modern archaeological investigation.
