Association of Friends of Grandson Castle

Founded in 1981, the Association of Friends of Grandson Castle (AACG) brings together nearly 300 passionate members who actively contribute to bringing one of French-speaking Switzerland’s major historic monuments to life. The association plays an essential role in the castle’s cultural life by organising the Grandson Medieval Festival.

The AACG committee, supported by enthusiastic volunteers, organises major events that open the castle to all audiences:

• The major Medieval Festival held in August, which attracts several thousand visitors each year.
• Cultural activities and events that make history accessible and bring it to life.

During the restoration period, the AACG is adapting its activities by offering:

• Exclusive tours of the restoration site for its members.
• Medieval workshops held outside the castle grounds.

In 2026, a major Medieval Festival will mark the reopening of the castle and the completion of the restoration work. Members will have the privilege of playing an active role in this landmark event.

Membership of the AACG gives you the opportunity to:

• Support a cultural project of significance to the region.
• Take part in exclusive events.
• Join a network of heritage enthusiasts.
• Contribute to the development of an iconic historic site.

For one weekend each year, step back into the heart of the Middle Ages: experience captivating music, forgotten flavours of medieval cuisine, stalls run by passionate craftspeople and colourful performances. A journey into history to share with family or friends in the exceptional setting of Grandson Castle.
