At Spring Garden in County Sligo, that is precisely what has happened. A circular earthwork roughly 21.7 metres across sits on a gentle rise in otherwise low-lying pasture, its enclosing bank of earth and stone, about four metres wide but only 0.4 metres high on the interior, folded into the existing field system along its south-western, western, and north-western arc. The original entrance has been lost entirely, and unlike many examples of its type, this one was built without a fosse, the encircling ditch that typically accompanies such enclosures.

Ringforts, known in Irish as raths when they are earthen, were the standard settlement form of early medieval Ireland, roughly the fifth to twelfth centuries. Most were farmsteads, enclosing a family's dwelling, outbuildings, and sometimes livestock within a raised bank that offered both a degree of defence and a clear social marker of landholding. The example at Spring Garden is modest in scale but carries one detail worth pausing over: the northern and north-eastern portion of the interior has been deliberately built up to create a level platform. Whether this was done in the early medieval period to manage the natural slope of the rise, or represents later intervention by farmers who found the space useful, is not recorded. What it suggests, either way, is that the site has been put to work across a long stretch of time, shaped and reshaped by whoever occupied the land around it, until the boundary between monument and field became more or less invisible.
