Sometimes a place is most interesting precisely because it has almost vanished. At Whitechurch in County Kildare, a field system of low earthworks and curving banks was recorded from the air in 1971, visible only as faint impressions in the landscape. By the time anyone looked closely on the ground, there was nothing left to see. Land improvement had removed the old field boundaries, replacing them with wire-and-post fencing, and no surface traces remained. What the aerial photograph captured was, in effect, the last legible moment of a layout that had already been erased.

The photograph in question, taken as part of the Cambridge University Collection of Aerial Photography in 1971 (reference CUCAP BGN 76), shows the earthworks sitting just off the crest at the eastern end of a low, east-west pasture ridge, immediately to the northwest of what appears to be an ecclesiastical enclosure. That enclosure is itself quietly remarkable. It contains a possible holy well, a graveyard, a medieval fortified church, and a baptismal font. A fortified church, sometimes called a church-tower or tower-church, was a pragmatic Irish response to the instability of the medieval period, the building itself serving as both a place of worship and a place of refuge. The field system, curving around the outside of this complex, suggests organised agricultural activity in close relationship with whatever community gathered here, though whether that relationship was medieval, early modern, or earlier still is not recorded.
