World Heritage

The UNESCO World Heritage Swiss Alps Jungfrau-Aletsch is one of the most spectacular mountain landscape of the Alps, an impressive example of the mountain formation with a vast spectrum of alpine and subalpine habitats. It embraces on its surface of 824 square kilometres almost the entire Bernese High Alps with its monumental rock massif in the territory of the cantons Berne and Valais. Nearly 90 % of the area of the World Heritage are covered by rock and ice. The UNESCO World Heritage Swiss Alps Jungfrau-Aletsch represents the wonderful natural beauties of the Alps. At its heart lies the impressive Eiger, Mönch and Jungfrau rock massif and the glacial landscape surrounding the Great Aletsch Glacier. On the southern slopes of the Bietschhorn, this high-alpine scenery is gradually transformed, over different altitudinal vegetation zones, into sub-mediterranean rocky steppes. This rich diversity of landscapes and ecosystems merges into an overall picture of outstanding beauty. Moreover the World Heritage area fulfils three out of four criteria defined by UNESCO to be inscribed as World Heritage property, emphasizing even more the values of the landscape. The 23 municipalities of the World Heritage property declared in the Charter of Konkordiaplatz to protect the aesthetic diversity and uniqueness of the area.
