This modest structure, catalogued as Mín na Saileach 4 in archaeological surveys, appears to be a clever adaptation of the natural landscape. Someone in the past recognised the potential of a large, naturally occurring stone and repositioned it to face the rock outcrop, creating a small enclosed space measuring just 1.2 metres by 2.1 metres, with a height of 0.8 metres.

The construction is remarkably simple yet effective; a low stone lintel has been carefully placed across part of the opening to provide a partial roof. While its exact age and purpose remain uncertain, the shelter could have served various functions throughout history, perhaps as a temporary refuge for shepherds, a storage space, or even a hideout during more turbulent times. The site's strategic position, offering views across the valley below, would have made it an ideal vantage point for anyone needing to keep watch over the surrounding landscape.

This humble structure represents the kind of vernacular architecture that dots the Irish countryside, where generations of inhabitants worked with the natural features of the land rather than against them. Dr Eugene Costello documented this site in 2016, adding it to the growing catalogue of small-scale archaeological features that help us understand how people lived and worked in rural Donegal through the centuries.
