Sion – Part 1

The Ancient Capital of Castles, Culture, and Sunshine

The city of Sion (in German, Sitten) is the capital of the canton of Valais, located in southwest Switzerland. With more than 7,000 years of history, it holds the title of the oldest city in the country. It is world-famous for its two fortified hills that rise spectacularly in the middle of the Rhône Valley.

📌 Quick Facts

  • The Sunniest City: Thanks to the high mountains around it, Sion has a unique microclimate with more than 300 days of sun a year.
  • Strategic Location: It sits on the flat floor of the Rhône Valley, surrounded by beautiful green hillsides covered in terraced vineyards.
  • Language Border: Although the canton of Valais is bilingual, Sion is predominantly French-speaking, located right next to the German-speaking area.

The Geography: How Nature Built a Natural Fortress

Sion did not become a major city by accident. Its location is a perfect example of how physical geography changes human history.

  • The Power of the Rhône River: Thousands of years ago, the Rhône Glacier melted and carved a wide, flat valley. In the past, the river was wild and often flooded the flat lands, creating dangerous swamps.
  • The Twin Hills (The Outcrops): In the middle of this flat, flooded valley, two massive rock hills stood high above the water. These hills are made of very hard rock that resisted the power of the ancient glaciers. For early humans, these hills were a gift from nature: they were dry, safe from floods, and incredibly easy to defend against enemies.
