On the open grassland of the Curragh in County Kildare, a modest earthwork sits quietly among one of Ireland's most unusual landscapes, largely unremarked by the thousands who pass through the area each year. It is a rath, the term for a roughly circular earthen enclosure, typically of early medieval date, defined by a bank and ditch that once served as the boundary of a farmstead or small settlement. This particular example is compact but well-defined: a circular interior roughly 21 metres across, enclosed by a fosse (a ditch cut into the earth) with an external bank, bringing the overall diameter of the whole structure to around 38 metres.

What makes the site quietly interesting is a detail recorded by the archaeologist Seán P. O'Riordáin in 1950, in what remains a significant survey of earthworks across the Curragh plain. Outside the bank on the western side lies a second fosse, which O'Riordáin noted was probably of modern origin rather than part of the original prehistoric or early medieval construction. The distinction matters: it means someone, at some point in the more recent past, dug a secondary ditch around an already ancient monument, for reasons that are no longer obvious. Whether this was drainage work, boundary marking, or something else entirely, the record does not say. The site is catalogued as Site Q in O'Riordáin's survey, and a scaled east-west section drawing was included in his published work, suggesting it was considered sufficiently intact to be worth recording carefully.
