Somewhere beneath a field at Hillfarm in County Kildare, there may be a burial mound that nobody has yet stood beside. Its existence is inferred entirely from the air: a circular cropmark roughly ten metres across, picked out in a aerial photograph taken in late June 2018. Cropmarks appear when buried features, walls, ditches, or mounds alter how the soil retains moisture, causing the grass or crops above to grow differently, and from above that difference reads as a ghost outline of whatever lies below. The circular shape here is consistent with a barrow, a low earthen mound typically raised over a prehistoric burial, though it could also represent a small enclosure of a different kind.

The photograph was taken on 28 June 2018 using Google Earth imagery, and it also shows a second cropmark to the north-west, this one suggesting a circular pond. Neither feature has been excavated or confirmed on the ground, and both remain provisional identifications. The site sits within the quietly agricultural landscape of Kildare, a county whose flat and well-drained soils have long made it good farming country and, consequently, a place where ancient earthworks have often been levelled or buried by centuries of tillage. What survives here, if anything does, survives invisibly.
