Ringforts, known in Irish as raths, are roughly circular enclosures defined by one or more earthen banks and ditches, built predominantly during the early medieval period between around 500 and 1000 AD. They served as farmsteads and defended homesteads for farming families, and their sheer number across the Irish countryside, estimated at somewhere between 40,000 and 50,000, makes them among the most common archaeological monuments in the country. That commonness, paradoxically, tends to make individual examples invisible, folded into fields and forgotten by anyone not specifically looking.

Mountshannon itself is a small harbour village on Lough Derg, the largest of the Shannon lakes, developed in the eighteenth century as a fishing and trading settlement. The surrounding countryside is typical of east Clare, a mix of low drumlin-like rises, old field boundaries, and land that has been continuously farmed for well over a thousand years. Ringforts in this part of Clare would have been the homes of early medieval freeholders and their extended families, sometimes enclosing a house, animal pens, and storage pits within the banked perimeter. The earthworks that survive today are the softened remnants of what were once more sharply defined boundaries, worn down by centuries of weather and agriculture but rarely entirely erased.
