Enclosures
There is a field in Corroy, County Mayo, that contains an enclosure nobody can see.
The ground is level pasture, unmarked and unremarkable underfoot, yet somewhere within it lies the ghost of a roughly triangular boundary, around 53 metres from north to south and 50 metres across at its wider southern end, narrowing to a point at the north. No bank, no ditch, no stone survives at ground level to hint at what was once enclosed here.
What makes the site particularly curious is its cartographic history. The Ordnance Survey mapped Ireland at six-inch scale in 1838, and again in 1930, and on neither occasion did the surveyors record any enclosure at this spot. It is only on the later 25-inch plan that a triangular form, defined by field boundaries, is indicated at all. This means the enclosure either escaped two rounds of detailed survey, or the boundaries visible on the 25-inch plan represent something that had already begun to disappear by the time anyone thought to note it down. The ridge location, with its commanding views across the surrounding landscape, is consistent with the kind of elevated, defensible ground that enclosed settlements and agricultural enclosures of various periods in Ireland tended to favour, though without excavation it is impossible to say what period, or what purpose, this particular example belongs to.
