Inis Gé Thuaidh, sometimes rendered in English as North Inishkea, is the larger of the two Inishkea islands lying in Blacksod Bay, and somewhere on its wind-scoured ground sits a recorded enclosure, the kind of feature that turns up on archaeological maps with a grid reference and a monument number, and very little else attached to it.

An enclosure in the Irish archaeological sense is broadly what it sounds like: a defined area set apart from its surroundings by a bank, wall, ditch, or some combination of these. What that boundary was meant to contain or exclude, and when, depends entirely on the site. On the Inishkea islands, human presence stretches back a considerable distance. Early Christian monks settled on the islands, and the remains of that monastic period, including traces of settlement and religious activity, have been documented across both islands. The Inishkeas were permanently inhabited into the twentieth century, the last residents leaving after a tragedy in 1927 when ten young men drowned during a sudden storm while fishing. Against that layered backdrop, an enclosure could belong to almost any period, ecclesiastical, early medieval, or later agricultural, and without excavation or detailed survey, its date and function remain genuinely open questions.

The island is uninhabited and accessible only by boat from the Mullet Peninsula, which means the enclosure sits in a place that demands some effort to reach. That remoteness is itself part of what makes sites like this quietly compelling: a feature substantial enough to be formally recorded, on ground that relatively few people walk across in any given year.
