Kunsthaus Zürich and Bührle Foundation Set New Provenance Research Guidelines
The Facts
On 26 May 2025, the Zürcher Kunstgesellschaft and the Foundation E. G. Bührle Collection announced a set of guidelines for the continued collaboration regarding the 205 works on long-term loan at the Kunsthaus Zürich. The agreement includes a five-year intensified provenance research project to be conducted by the Zürcher Kunstgesellschaft, aligning with recommendations from the 2024 Gross report. The Bührle Foundation reaffirmed its commitment to seek fair and just solutions for works with substantiated indications of Nazi-looted cultural property, including financial contributions to allow affected works to remain on view, as with Manet's 'La Sultane'. Three new exhibition formats will provide additional historical contextualization.
The Signal
This framework represents a significant institutional response to growing public and scholarly scrutiny of collections with Nazi-era gaps. By taking direct responsibility for provenance research and committing to transparent restitution processes, the Kunsthaus and Bührle Foundation signal a shift toward proactive accountability that may influence other museums with similar holdings. For collectors and curators, the agreement underscores the increasing importance of rigorous provenance documentation in maintaining public trust and institutional legitimacy. The continuation of the long-term loan ensures the Bührle collection remains accessible, balancing historical obligations with public engagement.
