Earthwork, Garbally (Coshma By.), Co. Limerick
Co. Limerick |
Ritual/Ceremonial
In a pasture field in the Coshma barony of County Limerick, a small circular earthwork sits in the ground, largely invisible at eye level and absent from the Ordnance Survey's historic mapping.
It has no marker, no signage, and no formal record drawn from anyone walking the land. The only reason it appears in the archaeological record at all is because a gas pipeline survey once flew over it with a camera.
The site, catalogued as Site No. 039142, was first identified during analysis of aerial photographs taken on 3 November 1984, as part of work connected to the Bórd Gáis Éireann Curraleigh West-Limerick gas pipeline. Cropmarks are the faint outlines that buried or levelled features leave on the surface vegetation above them, visible from the air when differential soil moisture causes crops or grass to grow in subtly different patterns. In this case, the photographs revealed the outline of a small circular earthwork, with a linear cropmark running east to west cutting across it at its northern edge. That intersecting linear feature adds a layer of ambiguity; it is unclear whether it relates to the circular feature or represents something else entirely, from a different period or function. A nearby enclosure, recorded separately as LI039-042, lies roughly 37 metres to the south-east, hinting that this particular patch of farmland may have been more intensively used in the past than the present pastoral scene suggests. The circular form was confirmed again in Ordnance Survey Ireland orthophotos taken between 2005 and 2012, and on Google Earth imagery, though its nature and date remain unestablished. The record was compiled by Fiona Rooney and uploaded to the Sites and Monuments Record in April 2021.
The site sits approximately 175 metres east of the Parkroe townland boundary, in ordinary farmland with no public access infrastructure. There is nothing to see from ground level, and the feature is not marked on any publicly available historic map. For anyone with an interest in landscape archaeology, the most practical way to engage with it is through the aerial and satellite imagery cited in the record, where the cropmark outline, faint but legible, can be traced against the surrounding field pattern.
