Ringforts
What looks like an ordinary field boundary in the pastureland of Dollas Upper, County Limerick, is doing quiet double duty.
Running along the northwest to southeast arc of a modern agricultural enclosure is the surviving remnant of an early medieval ringfort, a circular or oval earthwork bank originally built to enclose a farmstead and its inhabitants. The earthwork has been absorbed so thoroughly into the working landscape that the full circuit of the original monument is now only legible from above, appearing as a cropmark in aerial and satellite imagery, where differences in soil moisture and vegetation betray the buried line of the old bank where it is no longer visible at ground level.
The monument sits on the eastern side of a low rise in pasture, roughly 85 metres southeast of the townland boundary with Lisduff. When the Ordnance Survey recorded it on their six-inch map of 1840, the earthwork appeared as a suboval shape measuring approximately 50 metres east to west and 41 metres north to south. By the time the revised 25-inch survey was completed in 1897, the monument had already begun to be incorporated into a field boundary, and only a semicircular arc of around 43 metres was still clearly distinguishable. What makes this particular site of broader interest is its relationship to two neighbouring ringforts recorded nearby: one lies approximately 230 metres due west, another approximately 270 metres due east, and the three appear to sit in alignment. Whether that arrangement reflects deliberate planning, shared community organisation, or simply the coincidence of good agricultural ground is not recorded, but the pattern is suggestive.
The monument is not formally accessible as a visitor site and sits within working farmland, so any approach would require the landowner's permission. Aerial and satellite imagery, including orthophotos compiled between 2005 and 2018, offer the clearest view of the full extent of the earthwork, particularly where the cropmark traces the buried arc from southeast around through south and west to northwest. On the ground, the incorporated field bank on the northern and eastern sides is the most tangible feature. The research was compiled by Alison McQueen and Vera Rahilly and uploaded to the Sites and Monuments Record in October 2020.
