«La suisse n'existe pas» (Switzerland does not exist) – in this one key sentence Switzerland introduced itself at the World Exposition in Seville in 1992. This was because it is not uniformity, but variety in a small space that defines Switzerland. This can be explained culturally and geographically: In little Switzerland, four national languages are spoken in addition to numerous dialects. There is also a distinction between the culture in the mountains and the culture on the central plateau, while life in a mountain valley is different from that in the big city. So, although there are numerous regional traditions there are relatively few national customs. However, over time and with the increase in tourism, there are some local customs that have achieved national fame.
