These circular enclosures, known in Irish as raths, were the standard form of rural settlement across early medieval Ireland, typically consisting of an earthen bank and ditch enclosing a farmstead. Tens of thousands once existed across the country; a surprising number survive, often as low grassy rings half-noticed from a passing road, their original purpose long since replaced by a kind of ambient presence in the land.

Clare itself is particularly well furnished with such monuments, a reflection of the county's dense early medieval settlement. Raths were built and occupied roughly between the fifth and twelfth centuries, serving as enclosed homesteads for farming families of middling status. The bank provided a degree of security against livestock theft and signalled social standing as much as it offered physical protection. Over the centuries, many acquired a secondary life in local folklore as the dwelling places of the sídhe, the supernatural beings of Irish tradition, which helped protect them from deliberate demolition long after their original function was forgotten. The Tonavoher example belongs to this widespread and deeply embedded category of monument, one of the most numerous yet least individually documented in the Irish archaeological record.
