Kunsthaus Zürich and Bührle Foundation Agree on Provenance Research Framework for Long-Term Loan
The Facts
The Zürcher Kunstgesellschaft and the Foundation E. G. Bührle Collection announced on May 26, 2025, a new set of guidelines governing the long-term loan of 205 works from the Bührle Foundation at the Kunsthaus Zürich. The works will remain on public view, while the Kunsthaus will conduct a five-year provenance research project on the collection, applying its own standards and building on the 2024 report by Prof. Raphael Gross. 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 stay at the museum, as recently done with Manet's 'La Sultane'. Three new exhibition formats will be introduced to deepen historical contextualization.
The Signal
The agreement resolves a period of intense public debate and an independent review of the Bührle Foundation's provenance research, signaling a shift in institutional responsibility from the foundation to the museum. For collectors and curators, this sets a precedent for how contested collections can remain accessible while addressing historical claims through transparent, museum-led research. The commitment to fair solutions and continued public display may influence how other institutions handle similar long-term loans with problematic provenance, particularly in Europe where Nazi-era restitution claims remain a pressing issue.
