Inis Gé Thuaidh, the more northerly of the two Inishkea islands, sits in the Atlantic a few kilometres west of the Mullet Peninsula, exposed to weather that has long since discouraged permanent settlement. That the boundaries survive at all, in any legible form, is itself quietly remarkable.

The Inishkea islands were inhabited for centuries, with evidence of early Christian activity, seasonal fishing communities, and a population that persisted into the twentieth century. The last permanent residents left Inis Gé Thuaidh and its southern companion in 1931, following a tragedy in which ten young men from the islands drowned during a sudden storm while fishing. What remains on the ground, including the field systems, reflects the layered use of marginal Atlantic land across many generations. Field boundaries of this kind, typically constructed from cleared stone stacked into low walls or banks, served the practical purpose of dividing grazing from tillage, or marking one family's plot from another's. On an island like this, every workable patch of ground would have been carefully managed.
