About us

Weddings, private celebrations and seminars in the castle

Celebrate your wedding, a family celebration or a corporate evening with us at Château Mercier. For private occasions, we welcome 10 to 70 people and combine the salons of our historic castle with garden and terrace. Your wedding ceremony can take place in the garden, the subsequent reception on the terrace and the wedding dinner in the salons. Birthdays, anniversary celebrations with family and festive gala dinners also find their setting with us.

For your seminar, training or working session, two conference rooms are at your disposal: the Salle de l'Auvent for up to 20 people and the Salle de la Piscine for up to 50 people. Daylight, WiFi and presentation equipment support your collaborative work. We organise rooms, catering and, if desired, overnight accommodation through a central point of contact. You can plan a full or half-day seminar and combine your stay with shared meals.

Our kitchen creates seasonal menus for working lunches, banquets, aperitifs and festive dinners. We tailor the selection to your wishes. For your celebration, the castle can be completely privatised. Our 19 renovated guest rooms offer accommodation for up to 33 people; we host one group at a time. The next morning, you can gather for breakfast in the salons. The old park and the early 20th-century architecture accompany your event and provide a special setting for breaks as well.

A great castle with a very nice park. A bit difficult to access, you have to park rather in the city center and then walk your way up there. The castle is usually not open for visitors. The only thing worth seeing in Sierre!
