Rich in mountains, islands, glaciers, farmlands and fjords, Sogn og Fjordane is best known for Sognefjord, the longest in Norway and the second-longest in the world. One of its arms, Nærøyfjord, is a UNESCO World Heritage Site, as is the 12th-century Urnes Stave Church near Lustrafjorden, an excellent example of traditional Scandinavian wooden architecture. Jostedalsbreen, the largest glacier on mainland Europe, is home to a national park with several museums and visitor centers.
