Enclosure, Crean (Smallcounty By.), Co. Limerick

Enclosures
A circular enclosure in a Co. Limerick field went entirely unrecorded on historical Ordnance Survey maps, and might have stayed that way indefinitely had it not been for a gas pipeline.
The site, situated in reclaimed pasture in the townland of Crean in the Smallcounty Barony, belongs to a category of archaeological feature that can be invisible at ground level, showing itself only as a cropmark, the faint differential colouring that appears in grass or grain when buried features affect how plants grow above them. In this case, the enclosure presents as a circular cropmark, the kind of outline that typically signals a former ring ditch, ringfort, or enclosed settlement, though without excavation the precise nature and date of the feature remain uncertain.
The site came to light through an aerial photograph, reference BGE 1:5000 No. 47, taken on 3 November 1984 as part of survey work connected with the Bórd Gáis Éireann Curraghleigh to West Limerick gas pipeline. That infrastructure project, while primarily industrial in purpose, generated aerial coverage of a rural corridor that had not been closely examined before, and the photograph revealed what the historic maps had missed entirely. The enclosure was later confirmed visible on an Ordnance Survey Ireland orthophoto taken between 2005 and 2012, and again on a Google Earth image dated 20 September 2020, where the circular form can be seen bisected by a field boundary running northwest to southeast. The record was compiled by Martin Fitzpatrick and uploaded to the national sites register in March 2021.
Because the feature exists below the current ground surface, there is nothing to see in the conventional sense when standing in the field. The most accessible view remains the Google Earth orthoimage, where the cropmark is legible once you know what you are looking for. The bisecting field boundary is a useful orientation point, cutting across the circle and giving a sense of scale. If you are visiting the wider area, the enclosure lies approximately 200 metres south of a separately recorded enclosure, LI031-107, which may itself reward comparison. Late summer, when crops or grasses are under moisture stress, tends to be when cropmarks of this kind show most clearly in aerial imagery, so satellite imagery from that season offers the best chance of spotting the outline for yourself.
