Ringforts, known variously as raths or lios depending on local tradition, were the standard farmstead of early medieval Ireland, roughly from the fifth to the twelfth centuries. A family would have enclosed their home, their livestock, and their daily life within a raised bank and ditch, less a military fortification than a statement of ownership and a barrier against wolves and cattle raiders. Ireland has somewhere in the region of forty to fifty thousand surviving examples, making them among the most common archaeological monuments in the country, yet each one represents a specific family, a specific patch of ground, a specific set of daily decisions made over generations.

Knockaun is a small townland in Clare, and like many such places its name carries its own quiet history. The Irish "cnoc", meaning hill or hillock, appears in countless townland names across the country, often pointing to exactly the kind of slightly elevated ground that early farmers preferred for settlement, dry underfoot, with a good view of approaching visitors. The ringfort here would have followed that same logic, its builders choosing the site for practical reasons that still make sense when you stand on the ground and look around.
