Imagine a city that not only lies at the foot of majestic Alpine peaks but also seems to be literally built upon them. Sion, the capital of Valais, is such a place. Dominated by two imposing hills, each crowned with a historic edifice, this Swiss gem tells a story spanning thousands of years. From Roman legions to medieval bishops and Renaissance splendor, Sion is a living history book waiting to be discovered.
Sion's skyline is unmistakably defined by its two iconic hills. High above the city, the ruins of Château de Tourbillon are enthroned. This place, whispering tales of ancient power and noble intrigues, offers a panoramic view over the valley. It is a tangible reminder of Sion's rich history.
On the other hill stands the Basilique de Valère, a true fortified church. This impressive basilica houses one of the oldest playable organs in the world, dating back to the 15th century. Inside the historic Basilique de Valère, you'll also find the Valais History Museum. This museum tells the fascinating story of Valais, from prehistory to the present day, displaying artifacts that illustrate the lives of the Alpine people throughout the centuries. It offers a profound glimpse into the heart of the region.
Through the Ages: From Roman Forum to Renaissance Splendor
Once descended from the hills, Sion's lively city center unfolds. Here, on Place Maurice-Zermatten, the heart of the city beats. This spot, named after a local writer, has been a meeting point for centuries. Imagine Roman legionaries marching here, and later market vendors hawking their wares.
Not far from there lies the Place de la Planta, which is more than just a square. Here, under the shade of ancient trees, Roman gladiatorial contests were once held. The remains of an amphitheater are still hidden beneath the ground.
The city also houses architectural jewels such as the Maison Supersaxo, a Renaissance house built by the powerful Supersaxo family. It is famous for its wooden ceiling in the great hall, a masterpiece of 16th-century craftsmanship. The Château de la Majorie, once the residence of the Bishops of Sion, is also worth a visit. This elegant castle is now home to the Valais Art Museum, where art and history converge.
The grandeur of Sion Cathedral, with its mix of Romanesque and Gothic elements, has been a spiritual center for over a thousand years. Inside, you'll find beautiful frescoes and a serene atmosphere that invites contemplation.

Unexpected Discoveries: Nature, Film, and Dark Legends
Sion also surprises with its diversity. The Valais Nature Museum, housed in the former home of the de Kalbermatten family – an example of 16th-century bourgeois architecture – reveals the astonishing biodiversity of Valais, from ibex to rare butterflies.
An unexpected treasure in the heart of Sion is the Fondation Fellini pour le Cinéma. The legendary Italian filmmaker Federico Fellini had a special connection with Sion, and this foundation preserves his archives and celebrates his legacy, a magical place for film enthusiasts.
For those who love dark legends, there's the Tour des Sorciers, the 'Witches' Tower'. This imposing tower, once part of the city wall, later served as a prison and was the scene of the infamous witch trials in Valais. Its walls still seem to whisper tales of injustice and fear.
Conclude your exploration at the Marché de la vieille ville de Sion. This historic market, which has been the heart of the city for centuries, is a feast for the senses. Here you can taste local cheeses, admire artisanal products, and enjoy the lively bustle where tradition and daily life converge.
