Hailuoto

Finland's largest island in the Gulf of Bothnia, Hailuoto lies off the coast of Oulu in the northern Baltic and is classified as a nationally significant built cultural environment. The island's western tip holds the Marjaniemi lighthouse, and the Kirkkosalmi wetland area is a noted bird refuge where rare species are observed. Hailuoto is still expanding due to post-glacial rebound and will eventually connect to the mainland — a geological process that has been reshaping the island for roughly 1,700 years.
