Unopened Portfolios Reveal Swiss Museum’s Conceptual Art Gift Is Far Larger Than First Thought

A major donation of conceptual and minimalist art to the Musée des beaux-arts de La Chaux-de-Fonds in western Switzerland has turned out to be considerably larger than first announced, after museum staff finished cataloguing portfolios that had not yet been opened when the gift was first made public, the museum confirmed in reports published on 14 September 2026.

From 150 works to 218

The collection, donated by Swiss collector Philippe Bodenmann, was initially announced in 2025 as comprising around 150 works. The full total has since been confirmed at 218, spanning Anglo-American conceptual art, Zurich Concrete art and the Swiss Neo-Geo scene, with pieces by artists including Joseph Kosuth, Lawrence Weiner, Max Bill, Richard Long and Hamish Fulton. “When we first announced the donation project to the political authorities, not all of the portfolios had yet been opened,” said museum director David Lemaire. The donor placed no conditions on the gift beyond a request that the collection be kept and offered to the museum as a whole rather than divided.

On show until 2027

A selection from the gift, including Kosuth’s 1985 work Intentio (project) and an untitled monochrome relief by Andreas Christen, is on public display at the museum until 3 January 2027. La Chaux-de-Fonds, a former watchmaking centre in the Jura mountains best known internationally for its UNESCO-listed urban planning, has a small but internationally minded art museum that has periodically punched above its size through donations of this kind, rather than through acquisitions funded by its own budget.

Why It Matters

Museum donations are usually catalogued and valued before they are announced, so a gift that grows by nearly 50% after the fact is unusual. For a regional museum, the discovery hands La Chaux-de-Fonds a collection of international conceptual and minimalist art far beyond what its acquisitions budget could normally reach, potentially reshaping its standing among Swiss institutions built around 20th-century movements that are otherwise concentrated in larger national collections.
