Sion Old Town is a compact medieval centre where narrow lanes climb toward the city’s two famous hilltop landmarks: Valère and Tourbillon. The most important distinction for first-time visitors is that Valère is a fortified medieval borough centred on the Basilica of Notre-Dame de Valère and the Valais History Museum, while Tourbillon is the ruined bishop’s castle on the opposite hill. Together with the Cathedral of Notre-Dame du Glarier, historic squares, shops, cafés and the Friday market, they make the Old Town one of Sion’s most rewarding areas to explore on foot.
Quick Answer: Allow about 2–3 hours for Sion Old Town and Valère if you want time to walk the historic streets, enjoy the viewpoints and visit the basilica. Add more time for the Valais History Museum or the climb to Tourbillon Castle. Valère’s basilica and Tourbillon are separate sites on opposite hills.

What Is Sion Old Town Known For?
Sion’s Old Town sits below the hills of Valère and Tourbillon in the Rhône Valley. Sion Tourisme describes it as one of Switzerland’s best-preserved medieval towns, although the city’s history reaches much further back than the Middle Ages. The historic centre mixes old religious and civic buildings with shops, restaurants and terraces, so it still feels like an active part of the city rather than an open-air museum.
Useful landmarks include the Cathedral of Notre-Dame du Glarier, the Place de la Planta, Rue du Grand-Pont, the old fortification remains and the streets leading toward Valère. Switzerland Tourism dates the present Cathedral of Notre-Dame du Glarier mainly to the 15th century.
For visitors who prefer a structured walk, Sion Tourisme’s official Discovery Walk covers roughly 2.5 kilometres and is designed to take about 1 hour 15 minutes. It connects important sights around the historic centre and is a practical alternative to wandering without a plan.

The Rich History of Valère
Valère is often called Valère Castle or Château de Valère in tourism material, but the site is more accurately understood as a fortified medieval borough built around the Basilica of Notre-Dame de Valère. The cathedral chapter associated with Valère is documented from 1049, while construction of the present basilica began in the 12th century and developed through the 13th century.
The church combines Romanesque and Gothic elements. The houses surrounding it formed the medieval residence of the cathedral chapter, and a fortified enclosure with towers was added around the beginning of the 14th century. Pope John Paul II raised Notre-Dame de Valère to the rank of minor basilica in 1987.
Today, the fortified site contains the Basilica of Valère and the Valais History Museum. This makes Valère different from a conventional castle visit: the experience combines religious architecture, a medieval residential complex, museum collections and panoramic views over Sion and the Rhône Valley.

Getting Lost in Sion’s Narrow Streets and Alleys
Walking is the easiest way to experience Sion’s historic centre. The lanes rise gradually from the commercial streets toward the castle hills, passing older façades, small squares, restaurants, terraces and local shops.
If you visit on a Friday, the Old Town market adds another reason to explore in the morning. Sion Tourisme’s visitor information lists the market every Friday from 08:00 to 14:00 throughout the year. Food producers, merchants and other vendors occupy streets in and around the centre, giving the area a livelier atmosphere than on an ordinary weekday.
Comfortable footwear is useful because the Old Town includes cobblestones and the approach toward Valère becomes steeper. The climb is part of the experience, but visitors who have difficulty with uneven surfaces should check accessibility information before going.
The Magnificent Views from Valère
| Aspect | Metric |
|---|---|
| Location | Sion, Valais, Switzerland |
| Main landmark | Basilica of Notre-Dame de Valère and fortified medieval borough |
| Views | Sion, Rhône Valley, vineyards and surrounding Alps |
| History | Basilica mainly 12th–13th century; fortified enclosure developed around 1300 |
| Accessibility | Final approach on foot; historic cobbles, slopes and stairs may be difficult for reduced-mobility visitors |
Valère’s elevated position gives visitors broad views across Sion and the Rhône Valley. Vineyards climb the surrounding slopes, while mountains frame the valley beyond the city. Tourbillon Castle is also clearly visible from the Valère side, which helps explain why the two hills are so closely associated in images of Sion.
The views are one of the main reasons to make the climb even if you do not plan a long museum visit. Clear weather naturally gives the best mountain visibility, while lower light later in the day can make the stone buildings and vineyards more attractive for photography.
Valère or Tourbillon: What’s the Difference?
The names are easy to confuse because Valère and Tourbillon rise on neighboring hills above the same Old Town. They are separate historical sites with different purposes and visitor experiences.
| Site | What it is | Why visit |
|---|---|---|
| Valère | Fortified medieval borough centred on the Basilica of Notre-Dame de Valère | Basilica, medieval organ, Valais History Museum and views |
| Tourbillon | Ruined episcopal castle built around the turn of the 13th and 14th centuries | Castle ruins, chapel, hilltop views and a stronger fortress atmosphere |
Tourbillon was established by Bishop Boniface de Challant as an episcopal residence. A major fire that struck Sion in 1788 left the castle in ruins. The surviving site includes the well-preserved Saint-Georges and Saint-Grat chapel.
Tourbillon is seasonal. Its official site lists opening from March 15 to November 15, with longer daily hours from May through September, and closure from November 16 through March 14. Entrance to Tourbillon itself is listed as free.

Sion’s Old Town: A Hub of Culture and Tradition
Sion’s historic centre remains active throughout the year rather than functioning only as a sightseeing district. Restaurants, terraces, cultural venues, shops and public events share the same streets as medieval monuments.
The Friday Old Town market is one of the easiest recurring events for visitors to experience. Sion Tourisme describes it as the largest weekly market in French-speaking Switzerland. Summer also brings performances and events into the streets and squares.
Travelers who want more interpretation can book an official guided Old Town tour. Sion Tourisme’s tours can include the Cathedral of Notre-Dame du Glarier, St. Theodule Church, the Witches’ Tower, the Town Hall and other sites that may not always be accessible independently.
Uncovering the Secrets of Valère
The most unusual feature inside the Basilica of Valère is its medieval organ. Musées du Valais dates the instrument to approximately 1435–1437 and describes it as the oldest playable organ in the world. Its survival makes Valère more than simply a viewpoint or historic church.
The Valais History Museum occupies the surrounding medieval complex. An official museum tour describes a route through 27 rooms and around 1,000 displayed objects, using the collections to explain how the cultural history of Valais developed over time.
Some parts of the basilica can be experienced independently, while special areas such as the choir and treasury are included in certain guided visits. A free audio guide is also available for the basilica in French, German and English.
Official museum information: Musées du Valais.

Sion’s Old Town: A Culinary Delight
Sion is in the heart of Valais, so regional food and wine fit naturally into an Old Town visit. Raclette is one of the best-known Valais dishes: melted cheese is traditionally served with potatoes and accompaniments such as pickles. Local Valais wines are another regional specialty worth looking for on restaurant and wine-bar menus.
The Old Town contains restaurants, cafés and terraces, making it easy to break up a walk rather than completing the historic sights all at once. Menus and opening days change, so check current restaurant information if a particular dish or dining style is important to you.
How Long Should You Spend in Sion Old Town?
For most first-time visitors, 2–3 hours is a sensible planning estimate for the Old Town and Valère. That gives enough time to walk through the historic centre, climb to Valère, see the basilica and stop at the viewpoints without rushing.
Allow half a day if you also want to explore the Valais History Museum in detail or climb the opposite hill to Tourbillon. The official Sion Discovery Walk alone takes about 1 hour 15 minutes, so combining it with museum interiors and both hills can easily fill several hours.
Friday morning is especially useful if you want to combine sightseeing with the Old Town market. If your main concern is season and weather, see our guide to the best time to visit Sion.
Is Valère Worth Visiting?
Yes. Valère is one of the strongest reasons to explore Sion rather than treating the city only as a transport stop in Valais. The combination of the fortified medieval setting, Romanesque-Gothic basilica, medieval organ, History Museum and views gives the hill more variety than a simple castle viewpoint.
If your time is limited, walk through the Old Town and make Valère your priority. If you have half a day and are comfortable with additional uphill walking, add Tourbillon for the contrast between Valère’s preserved religious complex and Tourbillon’s ruined episcopal fortress.
