Works and work groups belonging to all phases of Jean Tinguely’s career are to be found in the museum's collection. Along with selected temporary loans, they afford the visitor an extensive view of the artist’s career. Apart from sculptures, the collection furthermore comprises a large number of drawings and letter-drawings, documents, exhibition posters, catalogues and documentation such as photographs. In the measure of the possible all the exhibits are accessible to the public and regularly shown, be it in the permanent collection or as loans to exhibitions worldwide.
The museum’s collections are the result of a generous donation by the artist’s widow, Niki de Saint Phalle, made on the occasion of its foundation, a donation of works from the Roche collection, as well as several other gifts and acquisitions.
