In fact, the adventure begins right here, in the immediate postwar period when even in Gressoney, after the birth of the first cable cars starting in the 1930s, there was a need to bring in the winter season to provide jobs for young people and keep the hotels open. The summer tourist season is already thriving at the time but not sufficient. The municipality and the resort company will take an active interest in finding funds and choosing the area for the construction of a 'mechanical plant. The area will be identified in Tschalvrinò.
On December 18, 1949, the SAGIT company will be formed with the participation of all the Gressoney people and some vacationers, thanks to which the weissmatten plant will see the light of day. It can proudly be said that the chairlift and the two adjoining ski lifts were built by the people of Gressoney. The chairlift was inaugurated on December 8, 1950. The new facility immediately attracted the attention of sportsmen from Lombardy, Piedmont, and Liguria.
After the chairlift, the Mure chairlift was built, then the Weissmatten chairlift , which, after three years, was moved to Ronken, later an intermediate station was built at Tschalfrinò, and the slopes were expanded and arranged. In 1980, the single-seat chairlift was replaced with a two-seat chairlift. From 2001, part of the red slope and walls were homologated for special slalom and giant slalom races of the FIS circuit, European Cup and World Cup. The two slopes were named after Leonardo David.
In 2009 the special slalom slope was approved for night competitions. In 2010, the European Cup women's special slalom night races and the World Military Championships women's giant slalom and special slalom night races were held.
