This one in Grahormick, County Wexford, does the opposite. Walk the pasture here and you would notice nothing unusual underfoot. The ringfort exists, in any practical sense, only from the air.

What aerial photography has revealed is the faint cropmark of an oval enclosure, roughly 40 metres along its northeast to southwest axis and about 30 metres across. It is defined by a single fosse, the term for the encircling ditch that was the primary earthwork of a rath, a type of ringfort typically associated with early medieval farmsteads in Ireland. Farmers of that period would have thrown the spoil from the ditch inward to form a bank, enclosing a domestic space within. At Grahormick, that whole arrangement has been reduced over centuries to a shadow visible only when ripening crops grow fractionally differently above the disturbed soil of the old ditch, a differential that a camera at altitude can catch but a person on the ground cannot feel. The site sits on a slight rise in an otherwise level landscape, which would have made it a sensible choice for settlement, offering a modest degree of visibility and drainage. The surrounding area shows other drain features in the same aerial image, suggesting a landscape that has been worked and reworked many times since whoever built this enclosure first broke the ground.
