Open Air Museums collect and re-erect old buildings at large outdoor sites, usually in setting of recreated landscapes of the past. The first one was King Oscar II’s collection near Oslo in Norway, opened in 1881 and is now the Norsk Folkemuseum.
Most open air museums are located in regions where wooden architecture prevail, as wooden structures may be translocated without substantial loss of authenticity. A more recent but related idea is realized in ecomuseums, which originated in France.
