Human activities change geographically and sociologically the territory they subject to colonisation. Until recently, in the middle of the 14th century, medium and high mountains have been subject to relatively peaceful occupation, mainly pastoral activities. The gradual development of recreation, elitist and then popular, has led to the definitive and sometimes complete conquest of these new areas, which are still ‘virgin’. Human grip has become increasingly strong and visible through development, urbanisation and construction, as more and more people embarked on the seasonal path from the villegiature, in contrast to the exodus of mountainous populations to valleys and cities. The city emerged on the slopes and in the heart of the mountains. Architecture has only increased in density. Changes in winter sports practices have influenced urban and architectural developments. Her study shows the steps she has travelled and crossed, embodied in different types of stations, which are themselves marked by a specific urban planning and architecture. Winter sports resorts, depending on the modes and uses, have taken different aspects and have had a greater or lesser impact on the landscape. Architectural experiments took place in turn, summoned or rejected models drawn up or invented in turn. In a roll-over game, we moved from a pioneering viller-station to a nostalgic village station.
