Penitentiary Exhibition Center in Sion: an outing that gets the children talking

An Old Prison Turned Art Venue

In Sion, the Exhibition Center of the Penitentiary intrigues even before you enter. The former prison has retained its stone charm and corridors, but it now hosts temporary exhibitions designed for the public, often related to art, history, or Valais heritage. The atmosphere is peaceful, conducive to discovery and discussions with your children.

What Your Children Will Discover

You go there for the unexpected. Depending on the programming, you will find contemporary works, historical objects, installations that play with light, sound, or materials. Children enjoy navigating the old cells, observing the details of the works, and asking questions: “What is this for?”, “Why this choice of colors?”. It’s sensory without being noisy, visual without being overwhelming. Ideal for sharpening observation, vocabulary, and imagination.

The Answers You Were Waiting For

• Ages: from 4–5 years if you like to take the time to explain. Perfect up to 12–14 years, and interesting for teens as well.
• Duration: count on 60 to 90 minutes depending on the exhibition and your family's pace.
• Type of activity: calm, cultural, and educational, sometimes with playful elements.
• Reservation and tickets: exhibitions are generally accessible without reservation. A paid entry is common for adults; children often benefit from reduced rates or free entry. Check the current conditions.
• Strollers and accessibility: the building is historic; accessibility may vary depending on the rooms and levels. A compact stroller generally fits, but a baby carrier may be more practical. Inquire about the accessibility of the current exhibition.
• Public transport: the old town of Sion is well served from the train station on foot or by bus. Public parking is available nearby at the bottom of the hill.
• What to bring: a water bottle, a small snack for after the visit, a sweater (some rooms are cool), and if you extend your visit with a walk in the old town, sun protection.
• Safety: serene environment, discreet supervision, and protected works. Just remind the children to look with their eyes.
• When to go: all year round, in overcast or cold weather. In summer, prefer the morning.
• Benefits for children: curiosity, vocabulary, sense of observation, understanding of the past, confidence in expressing themselves in front of a work, and a good dose of imagination.

Parents' Tips

• Start with a quick tour, then revisit 2–3 works that impressed you.
• Ask the children to choose “their” room and explain why.
• Take photos of the labels (without flash) to continue the discussion at home.
• Set a simple rule: we look, we whisper, we move forward together.
• Check the programming: some exhibitions offer family workshops on weekends.
