Linked, in the collective imagination, to the cold and snowy winter season, in reality these constructions were originally made as summer bases: functional, spartan, resistant structures, often used as granaries during the agricultural activities that animated the summer season. We are talking about chalets. The etymology can be traced back to the Swiss Romance language 'chalet' meaning shepherd's hut, but the term in turn derives from the pre-Roman word 'cala': a protected place, shelter. In fact, this type of multi-purpose building originated as a shelter, usually a single-storey building, used as a shelter by cattle breeders and consisting of a dwelling, stable for the animals, granary and store for provisions.
