Six small enclosures lie at Walterstown in County Kildare, visible not to anyone walking the ground but only from the air. They appear as subrectangular cropmarks, the kind of faint geometric outlines that show up in aerial photographs when buried features alter how vegetation grows above them. Buried ditches, for instance, tend to retain more moisture than the surrounding soil, producing a slightly lusher or differently coloured strip of crop or grass that only resolves into a recognisable shape when viewed from altitude. On the ground, there is nothing to see at all.

The six enclosures, recorded together as a cluster, sit on a low ridge in level, well-drained pasture. They were identified from a Geological Survey of Ireland aerial photograph, and at the time of a subsequent site visit no earthworks remained visible, the ground surface showing only heavy grass cover. Their subrectangular form places them within a broad category of enclosures found throughout Ireland, though without excavation their date and purpose remain open questions. Similar cropmark enclosures elsewhere in the midlands have proven to be anything from prehistoric settlements to early medieval farmsteads, but no such determination can be made here on present evidence.
