Field boundary, Gowlane, Co. Cork

What makes the spot quietly arresting is the partial visibility of it all: stone walls that have not quite vanished, protruding through the bog cover in fragments, some upright, some leaning, some swallowed almost entirely by gorse. The overall footprint of the surviving boundaries forms a roughly rectangular area of around 100 metres by 25 metres, oriented north-north-west to south-south-east, but the walls themselves are curvilinear rather than rigidly straight, following the logic of the land rather than any geometric plan.

What survives is a relict field system, meaning it belongs to an agricultural landscape that was abandoned and subsequently sealed beneath accumulating peat. The walls vary considerably in scale, ranging from about 20 to 60 centimetres thick and between 10 and 75 centimetres in height above the present surface. A particularly notable construction technique is visible in places: upright slabs set end-on into the wall line, a method sometimes described as orthostat construction, in which large flat stones are planted vertically rather than laid horizontally. This approach appears in Irish field systems across a broad span of prehistory and the early medieval period, though without excavation or additional dating evidence it is not possible to assign a precise age to the Gowlane boundaries. Some of the upright slabs have begun to lean or have toppled altogether, while other sections of wall survive only as large stones half-buried under gorse, their alignment still faintly legible if you look along the slope rather than directly at them.
