The Unesco World Heritage Centre is located on the Jungfraujoch - the top of Europe. What was long overdue finally became reality in December 2001: the region of the Jungfrau-Aletsch-Bietschhorn finally was accepted as one of UNESCO Natural Heritage Sites, the first area in the Alps to have been given this honor.

The magnificence of this universe of ice, rocks, alpine flora and forest can be felt if one traverses the Aletsch Glacier, with its 23 km the longest ice flow in the Alps. After descending from Riederalp by crossing the Aletsch Forest with its gnarly trees centuries old one all of a sudden stands right on the edge of the glacier.

This is the most glaciated part of the Alps, containing Europe's largest glacier and a range of classic glacial features such as U-shaped valleys, cirques, horn peaks and moraines. It provides an outstanding geological record of the uplift and compression that formed the High Alps. The diversity of flora and wildlife is represented in a range of Alpine and sub-Alpine habitats and plant colonization in the wake of retreating glaciers provides an outstanding example of plant succession. The impressive vista of the North Wall of the High Alps, centred on the Eiger, Mönch and Jungfrau peaks, has played an important role in European art and literature.
