The stave churches constitute a particularly valuable part of the Norwegian architectural heritage, and are considered to be of global as well as national importance. Their construction and richly decorated carvings show some of the finest craftsmanship to be seen anywhere in Norway. They also show many examples of how impulses from abroad were incorporated into Norwegian architecture. Urnes stave church is on UNESCO's World Heritage List. Like other medieval buildings and installations, the stave churches are automatically protected under the Cultural Heritage Act.
