Enclosures
At Dromkeen in County Limerick, there is an ancient enclosure that exists, for all practical purposes, only in a single aerial photograph taken nearly four decades ago.
The monument has never appeared on Ordnance Survey historic maps, was not visible on orthoimagery captured between 2005 and 2013, and by the time a Google Earth image was taken in June 2018, the ground above it had been planted with forestry. The site survives in the record not because anything can be seen there today, but because a survey aircraft happened to pass over at the right moment, in the right season, and caught what the soil had quietly been holding.
An enclosure in this context refers to a roughly bounded area, typically circular or oval, defined by a raised bank, ditch, or wall, and associated in Ireland with a wide range of periods and purposes, from prehistoric settlement to early medieval farmsteads. This particular example was identified as a roughly oval-shaped cropmark during the Bruff aerial photographic survey in 1986, recorded as image AP 4/3717 in the Bruff 258 series. Cropmarks appear when buried features, such as ditches or banks, cause the vegetation above them to grow differently, revealing outlines that are invisible at ground level but legible from the air, particularly during dry summers when soil moisture differences become pronounced. The enclosure sits in low-lying, wet pasture cut by land drains and watercourses, a landscape that would have looked very different to whoever occupied or enclosed this ground originally. A second enclosure, registered separately as LI023-164, lies approximately 145 metres to the northwest, suggesting this was not an isolated feature but part of a broader pattern of activity in the area. The record was compiled by Alison McQueen and Vera Rahilly and uploaded to the national monument database in September 2020.
For anyone attempting to locate the site today, the forestry planting that has obscured the monument on recent satellite imagery makes ground-level investigation unrewarding. The surrounding terrain is wet and low-lying, cross-cut by drainage channels, and the enclosure itself leaves no visible surface trace. The most informative way to engage with the site is through the 1986 aerial survey image, where the oval outline can be read in the crop or vegetation pattern of what was then open pasture. That image is the monument now, in any meaningful sense.
