Earthwork, Clonagh, Co. Limerick
Co. Limerick |
Ritual/Ceremonial
A circular mark roughly 35 metres across sits in reclaimed grassland in County Limerick, visible not to the naked eye so much as to the satellite.
It does not announce itself with standing stones or an interpretive panel. What gives it away is the faint outline caught in aerial and satellite imagery, the kind of trace that only becomes legible when you are looking straight down from above.
The earthwork was identified from a sequence of orthophotographic sources, including an Ordnance Survey Ireland image taken between 2005 and 2012, a Digital Globe orthoimage from 2011 to 2013, and Google Earth imagery, all of which preserve the circular outline. Orthophotos are geometrically corrected aerial or satellite photographs, scaled and oriented so that distances can be measured accurately across them, and they have become one of the more useful tools for detecting earthworks that have been all but levelled by centuries of farming and drainage. The record was compiled by Caimin O'Brien, drawing on details provided by Jean-Charles Caillère, and uploaded to the national monuments database in July 2021. A small stream running roughly 40 metres to the west marks the townland boundary with Ballykenry, and approximately 350 metres to the south-east lies Clonagh Monastery, a separate complex of recorded monuments that suggests this corner of Limerick had some significance over a long period.
There is no formal access point or waymarked route to this spot, and on the ground there may be little or nothing to see. The surrounding land is reclaimed grassland, which means drainage and agricultural improvement have likely reduced whatever original earthen banks or ditches once defined the circle. The site is best appreciated by examining the satellite imagery through publicly available mapping tools before visiting the broader area. Anyone with an interest in the monastic landscape of early medieval Limerick might combine a look at this location with the nearby Clonagh Monastery remains, keeping in mind that access to agricultural land requires the landowner's permission.
