Enclosures
Beneath a field in Garryclohy, County Tipperary, the outline of a large circular enclosure lies essentially invisible at ground level, yet from above it resolves into something unmistakable.
The site, roughly 105 metres in diameter, is known only as a cropmark, a phenomenon where buried ditches and banks affect the growth of crops above them, producing subtle but readable variations in colour and height that become legible in aerial or satellite imagery. What makes this particular site quietly remarkable is not just its scale but the presence of a second, roughly concentric fosse, a ditch, running parallel to the inner one at a distance of around 20 to 25 metres along its southern and western arc.
The enclosure was identified by Jean-Charles Caillère while examining Apple Maps satellite imagery, a reminder that significant archaeological features continue to be located through careful scrutiny of publicly available sources rather than formal excavation campaigns. The site sits in tillage land, which is precisely the condition that makes cropmarks legible; ploughed and planted ground responds more visibly to what lies beneath than permanent pasture would. The double-fosse arrangement, with an inner ring and a partial outer one, is a configuration sometimes associated with high-status prehistoric or early medieval enclosures in Ireland, though without excavation or dating evidence, the site's age and function remain open questions.
Because the enclosure exists only as a cropmark, there is nothing to see from the ground. The field presents as ordinary farmland, and the ditches that define the rings have long since been ploughed flat or silted over. The site's real existence, for now, is entirely in the aerial record.
