In a field of pasture near Tullerstown in County Wexford, there is a ringfort, or rath, that leaves no trace whatsoever at ground level. The only evidence of its existence is a faint mark in the vegetation, caught on an aerial photograph, where the grass grows fractionally differently above the buried remains of a circular enclosure roughly thirty metres across.

The mark traces what appears to be a fosse, the shallow ditch that would once have defined the outer boundary of the enclosure, curving around from the south-west through to the north. Ringforts of this kind were the standard farmstead of early medieval Ireland, typically housing a single family and their livestock within a raised bank and surrounding ditch. Thousands survive across the country in varying states of preservation, but many others have been reduced over centuries of ploughing and grazing until the earthworks disappear entirely into the soil. This one sits on a gentle slope facing south and east, a position that would have made practical sense to anyone choosing a sheltered, well-drained spot for a homestead. The site at Tullerstown belongs to this quieter category of monument, present in the record but effectively erased from the landscape.
