Owey Island was full-time inhabited up to the mid 1970s. Later on it only had part-time residents, mainly at summer. Most of them own old cottages inherited by ancestors who used to permanently live in the island.
History
Plenty of fish in the waters surrounding the island and the land that, fertilized with seaweed, was suitable for growing vegetables, allowed a simple lifestyle to more than 100 people. Turf was used to heat the homes; some of the islanders used it also to heat the equipment to produce single malt and liquors.[2]
In the olden days Owey had a post office and a school, which closed in 1971; its remains are still there. It had just one teacher in charge of the primary education of all ages, while for their secondary education children had to be sent to the mainland.
