Somewhere in the flat, waterlogged pastureland outside Moyvally in County Kildare, there may once have been a circular enclosure, though by the time anyone thought to look closely, it was already gone. What we know of it comes almost entirely from a single aerial photograph taken in 1973, which caught the western half of what appears to have been a roughly circular earthwork, the kind of feature that reads clearly from the air but can be nearly invisible at ground level, particularly on low-lying, poorly drained land where differences in soil moisture and crop growth do the work of revealing buried or levelled structures.

By 1985, fieldworkers found no visible surface trace of the monument at all. Local information pointed to the 1970s as the period when the field was cleared, meaning the enclosure, whatever its age or original purpose, was removed within just a few years of the photograph that first recorded it. Circular enclosures of this type in Ireland are often associated with early medieval settlement, sometimes enclosing a ringfort or a small farmstead, though without excavation it is impossible to say what this particular feature represented or how old it was. The aerial photograph reference, GSI N598-9, remains the sole direct evidence that anything was ever there.
