Enclosures
On a north-facing slope in Cloonlyon, County Mayo, there is a place where nothing can be seen.
The ground is flat, the pasture unbroken, and yet the cartographic record tells a different story entirely. What makes this site quietly arresting is precisely that absence, and what it implies about the speed with which an ancient feature can disappear from the landscape within living memory.
The 1837 Ordnance Survey six-inch map recorded a circular embanked enclosure roughly thirty metres in diameter at this spot. It was almost certainly a rath, the term used for a ringfort, a type of enclosed farmstead typically built during the early medieval period in Ireland, usually defined by one or more earthen banks and ditches. By the time the next major edition of the map was produced in 1919, the northern half of the enclosure had already been removed. What remained was shown as a hachured semi-circle, curving from east to west-southwest, measuring around twenty-five metres across. At some point after that, the rest was levelled too. Today there is no visible trace at ground level, the site sitting in open pasture with forestry planted just to its south. The transformation from a recognisable ancient monument to an unmarked field happened within a single mapping interval, somewhere between the mid-nineteenth and early twentieth centuries.
