As of 2020, there are seven World Heritage Sites in Finland. The United Nations Educational, Scientific and Cultural Organization (UNESCO) World Heritage Sites are places of importance to cultural or natural heritage as described in the UNESCO World Heritage Convention, established in 1972. Finland accepted the convention on 4 March 1987, making its historical sites eligible for inclusion on the list. The first two sites added to the list were Old Rauma and the Fortress of Suomenlinna (pictured), both in 1991, at the 15th Session of the World Heritage Committee. Six of Finland's sites are classified as cultural sites according to the UNESCO criteria, while one, the High Coast / Kvarken Archipelago, is a natural site. This is a transnational site and is shared with Sweden. In addition to its World Heritage Sites, Finland also maintains six properties on its tentative list. (Full list...)
