These circular earthworks, known variously as raths or ringforts, were the dominant form of rural settlement during the early medieval period, roughly 500 to 1000 AD. A typical example consists of a raised circular bank of earth, sometimes reinforced with stone, enclosing a farmstead where a family would have kept their livestock overnight and conducted the business of daily life. They are so common in the Irish countryside that many survive simply because farmers have worked around them for generations, their banks too stubborn or too unnerving to remove.

The Rahona example is recorded as a rath, the Irish term for an earthen ringfort, distinguishing it from a cashel, which is the stone equivalent more commonly found in the rocky terrain of the Burren and other parts of Clare. Beyond its classification and location, detailed information about this particular site remains largely inaccessible in the public domain. What can be said is that Rahona, like many Clare townlands, sits within a county that contains a remarkable density of early medieval remains, a reflection of the region's significance as a settled and organised landscape long before the arrival of the Normans.
