Embanked enclosure, Killowen, Co. Wexford

There is an early enclosure in Killowen, County Wexford, that you cannot see by standing in the field where it lies.
Walk across the ground today and there is nothing to read in the landscape, only cereal crop growing over whatever once stood here. The enclosure's existence is known from two sources separated by nearly two centuries: a cartographer's mark on the 1839 edition of the Ordnance Survey six-inch map, and a cropmark captured in a satellite image from July 2018. That is the full extent of its visible life.
The 1839 OS map records it as an embanked enclosure with an external diameter of approximately 35 metres. An embanked enclosure of this kind is broadly comparable to a rath, the circular earthwork farmstead that was the most common form of enclosed settlement in early medieval Ireland, defined by one or more earthen banks and ditches. What distinguished it from the raths recorded nearby is unclear. Two such sites sit close at hand: one roughly 50 metres to the west-southwest, another possible example around 160 metres to the east-southeast. The clustering suggests this part of a gently south-westward-facing slope in Wexford was once a settled and organised landscape, with a stream running some 200 metres to the south-west. By the time the cropmark was photographed via satellite, the bank itself had long since been levelled, but the buried ditch or disturbed soil left its outline in the differential growth of the crop above it, briefly legible from altitude in the summer heat.
Cropmarks of this kind appear most reliably during dry spells in summer, when crops growing over shallow, moisture-retaining ditches stay greener or grow taller than those rooted in more compacted, drained ground. The 2018 image caught the enclosure at precisely such a moment, preserving in digital form something the physical landscape no longer holds.
