The rath at Knock in County Clare is one such site, a circular earthwork enclosure of the kind that served as a defended farmstead during the early medieval period, roughly between the fifth and twelfth centuries. These structures typically consist of one or more banks and ditches thrown up around a central living area, the bank built from the soil and rock dug out to form the ditch. They were the homes of farming families across the Irish countryside for centuries, and the sheer number that survive, many still clearly visible as raised rings in fields and pasture, speaks to how thoroughly they shaped the rural landscape of early Christian Ireland.

The Knock rath sits in a county already well supplied with early medieval remains, Clare being a place where the physical evidence of that period has survived in unusual density. The word "rath" itself is simply the Irish term for this type of enclosure, used interchangeably with "ringfort" in archaeological literature, and it appears frequently in place names across the country as a marker of where these settlements once stood or still stand. Beyond its classification and location, the documentary record for this particular site remains sparse at present, and the details of its dimensions, condition, and any associated finds or features are not currently available in published form.
