With the increasing number of climbers, steps had to be taken to make the approach to the mountains a little less complicated and exhausting. Until mountain huts were built, there had been no choice for the climbers other than sleeping in the highest chalets or in a Bivouac shelter under some overhanging rocks and, in both cases, firewood had to be carried up. The Swiss Alpine Club during the first twenty-five years of its existence contributed to build thirty-eight huts, of which the oldest was the Grünhorn hut on the Tödi (1863), followed by the Trift hut, near the Dammastock (1864). The Matterhorn hut was built in 1865, the Mountet in 1871, the Weisshorn Hut in 1876, the Concordia on the Aletsch glacier and the Boval hut in 1877.
