Known in Irish as a ráth, a ringfort is a roughly circular enclosure defined by one or more earthen banks and ditches, built primarily during the early medieval period, between roughly the fifth and twelfth centuries. They served as farmsteads and homesteads for families of varying social rank, and tens of thousands of them once dotted the Irish countryside. Most have been partially levelled by centuries of agriculture; those that survive intact tend to do so in marginal land, on slopes or in corners of fields where a plough could not easily reach.

The townland name Parknamoney offers a quiet clue to the local landscape. In Irish placename conventions, "park" often derives from "páirc", meaning a field or enclosed piece of land, though the full etymology here remains uncertain without further documentation. Clare is unusually rich in early medieval earthworks, a county where ringforts cluster densely across the drumlin and limestone terrain of the Burren and its surrounding parishes. The rath at Parknamoney belongs to that broader pattern, a surviving trace of a farming settlement that may be well over a thousand years old, though without detailed fieldwork its precise form, condition, and date cannot be confirmed.
