That combination is not unusual in Cavan, a county whose drumlin landscape, formed by glacial drift into low rounded hills, has a habit of absorbing earthworks into the scenery until they are nearly invisible.

An enclosure, in the archaeological sense, is broadly any defined area bounded by an earthen bank, ditch, wall, or some combination of these. In Ireland they appear across thousands of years of settlement, from prehistoric farmsteads to early medieval ringforts, and distinguishing one type from another often requires excavation or at minimum a careful survey. Beagh Glebe, as a townland name, carries its own small clue: the word "glebe" refers to land historically attached to a parish church and set aside for the use of its minister, suggesting the area was shaped at least in part by post-Reformation land arrangements. Whether the enclosure predates that association by centuries or millennia is, for now, an open question.
