An important chapter in the history of alpinism, even if it may seem strange, was written by Berlin mountaineers. The mountains around Zillertal and the Otztal were opened to tourism in the last century thanks to the enthusiasm of the Berlin eople for the mountains. Here they built roads and refuges and in the Alps they opened climbs that nowadays are referred to as the "classics", such as Cresta Bianca on Pi Bernina or the Peuterey on Mount Blanc. Before the end of the 19th century the Berlin mountaineers built 65 routes in the western Alps. In the thirties instead, they were among the members of the expeditions to the Andes and the Himalaya. But the monument which recalls the love of the Berlin citizens for the mountains is in the Zillertal where they began their activity.
