About This Island

Ardoilean Island is a unique investment opportunity. The property, also known as High Island, is an expanse steeped in history, with archaeological artefacts inundating the ~79-acre plot. Foremost, church remnants on the island correlate with early Iron Age settlements. There is also the foundation of a monastery on Ardoilean’s southwestern edge that dates back to the seventh century. Other examples of historical relics are the remains of an old water mill, a granite globe, and a long-disused copper mine shaft. Beyond its historical reputation, Ardoilean endures as an island of immense natural value – serving as a haven for a vast array of birdlife. Fulmars, petrels, shearwaters, gulls, and oyster catchers live on the island. Barnacle geese also visit during the winter. There is a more modern building near Ardoilean’s southern landing area. A septic tank also suggests future building potential, though any construction would be subject to the necessary planning constraints. Due to its historical value, the resident monastery is not part of the sale. Regardless, the opportunity to own the surrounding island – one of such historical significance – is nothing short of rare.
