Enclosures
In a rough, poorly drained field in Lisheen, County Limerick, there is an ancient enclosure that you cannot see.
It does not appear on any Ordnance Survey historic maps, it does not show up on satellite imagery taken between 2011 and 2013, and it was invisible again when Google Earth photographed the area in June 2018. The only reason anyone knows it exists is because a plane flew over at the right moment in 1986 and the ground told the truth.
That moment of visibility came during the Bruff aerial photographic survey, when the site was recorded as a circular-shaped cropmark, catalogued as Bruff 129, AP 4/3721. Cropmarks of this kind appear when buried features, such as the ditches or banks of an old enclosure, affect how vegetation grows above them. Soil disturbed by ancient digging tends to retain more moisture, encouraging slightly lusher, taller growth; compacted banks beneath the surface do the opposite. From the air, under the right conditions of drought and low sun, these differences in vegetation register as faint outlines that reveal the shape of something long gone at ground level. In this case, the outline was circular, the signature of a class of monument found across Ireland that includes ring forts and enclosed farmsteads of the early medieval period, though the notes do not specify a date or function for this particular site. A related enclosure, recorded separately, lies just 42 metres to the north-east, near a townland boundary with Nicker.
Accessing the site means crossing working farmland in an area of rough, waterlogged pasture with forestry nearby, so any visit would require landowner permission and suitable footwear for ground that does not drain well. There is, practically speaking, nothing to see once you arrive. The value here is less in the experience of standing on the spot and more in what the site represents: a piece of the landscape that slipped through every layer of documentation except one aerial photograph taken on a single afternoon nearly four decades ago. Compiled by Alison McQueen and Vera Rahilly and uploaded to the record in July 2020, the entry exists as a quiet reminder that Irish fields hold a great deal that the usual methods of looking simply miss.
