High Coast / Kvarken Archipelago, a UNESCO World Heritage site in Finland and Sweden, recognized in 2000 and extended in 2006, is a Baltic coastal region showcasing dramatic post-glacial rebound, with land rising since the Ice Age. The High Coast’s rugged cliffs contrast with Kvarken’s shallow archipelago of moraine islands, hosting unique ecosystems and geological formations. This transnational site reflects Scandinavia’s natural heritage, offering a vivid record of Earth’s geological evolution and adaptation.
