Enclosures
On the Ordnance Survey six-inch maps, which recorded Ireland's landscape in extraordinary detail across successive editions, this enclosure in Tanrego, County Sligo, simply does not appear.
It was not noticed by the surveyors, or at least not committed to paper, and it took aerial photography to bring it back into any kind of official reckoning. That absence from the cartographic record is itself a quiet curiosity, suggesting a feature so well absorbed into the land that ground-level observation passed it by entirely.
What aerial photography revealed is an oval enclosure sitting at the northern end of a small, narrow ridge in rolling pasture. It measures roughly 46 metres along its longer north-northwest to south-southeast axis and about 38 metres across. Enclosures of this kind, defined by earthen banks or scarps rather than standing walls, were built throughout prehistoric and early medieval Ireland for purposes that varied, settlement and stock management among the most common. Here, the defining elements are two scarps of noticeably different scales. On the western through northern and eastern sides, a scarp roughly two metres high makes use of the natural fall of the ridge, so that topography and human construction are folded together. On the southern arc, a much lower scarp, only about a quarter of a metre, carries a very slightly raised internal rim. At its foot lies a shallow depression around four metres wide, possibly the remnant of a fosse, which is a defensive or boundary ditch, now largely filled in by centuries of soil movement and agricultural disturbance. No original entrance survives in a recognisable form, which is common enough in earthwork enclosures that have endured this long without excavation or formal protection.
