Foundation

As a museum institution, the Foundation works to deepen knowledge of the castle’s heritage values and to ensure they are passed on in an authentic and inclusive way, through both its collections and the scientific, cultural and historical content associated with them.

The Foundation also operates the site, ensuring that it remains open to the public and offers a sustainable programme of activities. It is firmly committed to playing an active role in the region’s tourism, economic and social development, in close collaboration with the local community.

Its original exhibitions, unique collection of crossbows, diverse events and wide range of activities allow a broad audience to enjoy a memorable experience that is renewed with every visit.

Expertise: The Grandson Castle Foundation strives for excellence in fulfilling its missions. It is committed to providing the highest quality products and services and ensures the continuing professional development of its staff in order to meet current professional standards.

Inclusion: By ensuring access to its facilities and content, the Foundation is actively committed to welcoming the public in all its diversity. It also develops its activities with the participation of its partners and audiences in order to encourage engagement and inclusion. It promotes employability while respecting diversity.

Responsibility: The Grandson Castle Foundation operates transparently and fulfils its responsibilities towards its staff, audiences, authorities, institutions and partners. It develops its activities with respect for the traditions and heritage entrusted to its care, with a view to ensuring the long-term sustainability of the site and maintaining a social commitment towards the people and organisations that depend on it.

Commitment: The Foundation carries out its missions and upholds its values with enthusiasm and authenticity. The passion with which it develops its activities contributes to the profile of the site and strengthens the engagement of its audiences and partners.

Curiosity: The Foundation encourages curiosity, the desire to learn, critical reflection and openness to others. It remains attentive to trends and societal changes while continually renewing its interest in the history of the castle, the region and the people who shape it, and works to pass this curiosity on to its audiences.

Synergy: The Grandson Castle Foundation is part of a network of individuals and academic, tourism, economic, cultural and social institutions. It encourages exchange in order to create cross-disciplinary projects and develop synergies related to the missions it has set itself.

2025 was the final year in which the castle remained open while restoration work was under way. The Grandson Castle Foundation therefore continued its commitment to keeping the restoration project open and accessible to the public, maintaining an active programme of educational activities until the site closed completely in September of that year.

The annual report looks back on the events of a pivotal year, just a few months before the major reopening of Grandson Castle on 2 March 2026.
