On a north-facing slope in Curraghduff, County Waterford, there is a low spread of stones that once formed the walls of a hut, and which still holds its roughly circular shape after what may be centuries of slow collapse. What makes it quietly puzzling is the absence of any identifiable entrance. Most ancient stone structures of this kind, whether simple shelters used by herders or more permanent dwellings, preserve at least some trace of where people came and went. Here, none has survived, or perhaps none was ever obvious to begin with.

The remains form a subcircular footprint, with external dimensions of roughly 9.1 metres east to west and 8.3 metres north to south, enclosing an interior space of approximately 6.6 by 5.7 metres. The whole thing is now blanketed in heather and sits in pastureland, which accounts for both its preservation and its easy overlooking. Hut sites of this general type in Ireland range from prehistoric shelters to early medieval booley huts, the latter being temporary structures used during transhumance, the seasonal movement of livestock to upland grazing. Without excavation, it is rarely possible to assign a precise date to surface remains this slight, and Curraghduff offers no obvious clues to narrow it down.
