There is nothing to see, no stone, no outline, no earthwork, yet the place has a name that carries its own quiet weight. Locally it is known as a "kill", a word derived from the Irish "cill", meaning a small early church or monastic cell, often associated with the earliest centuries of Irish Christianity. The designation survives in placenames across the country, sometimes attached to ruins, sometimes, as here, to ground that has long since been absorbed into ordinary farmland.
