Enclosures
Beneath a field of grazing land at Knockaloura in County Galway, the outline of a large circular enclosure has been quietly preserved, invisible to anyone walking across it but legible from the air.
The site exists, for now, only as a cropmark, the faint differential in how grass or crops grow over buried features, where the soil above an ancient ditch or bank retains slightly more moisture and nutrients, colouring the vegetation above it a shade or two differently from the surrounding ground. What appears in aerial imagery is a subcircular enclosure roughly 72 metres east to west and 64 metres north to south, making it a substantial feature by any measure.
The enclosure was identified and reported by Jean-Charles Caillère, who spotted it in Google Earth aerial imagery dated March 2014. It is also faintly discernible in earlier OSi DigitalGlobe imagery from between 2011 and 2013. Enclosures of this general type, ringforts or their precursors, were common across early medieval Ireland as enclosed farmsteads or places of habitation, though without excavation it is impossible to say with certainty what period this particular feature dates to or what purpose it served. Its size places it at the larger end of what might typically be expected, and the subcircular shape, slightly irregular rather than a true circle, is not unusual for earthwork enclosures of this kind. That it survives at all as a cropmark suggests the underlying archaeology has not been severely disturbed, even if nothing is visible at ground level today.
