Sion (or Sitten in German), the capital of the Canton of Valais, is known as the most sun-blessed town of Switzerland. Thanks to its central location, the small town abounding with culture is also an ideal starting point for exploring the summer and winter holiday resorts in the Valais side valleys.Sion is recognizable from afar thanks to the high towers of Castle Tourbillon and the Castle of Valeria. These landmarks guard the capital of Valais and its 30,000 inhabitants. Past and future blend in one of Switzerland’s oldest cities. Sion, which boasts a 7,000-year history, is today the economic center of Valais and an important traffic junction with its own international airport. The Castle Church of Valeria has one of the world’s oldest playable organs from the late beginning of the 15th Century.
