Its collec­tion includes paint­ings, draw­ings and sculp­tures from the early 15th century to the present. The museum consists of three build­ings: Hauptbau, Gegen­wart and Neubau. The former was opened in 1936 as a collec­tion-only building and expanded in 2016 with the Neubau across the street, where special exhi­bi­tions and collec­tion presen­ta­tions are displayed. The Gegen­wart building has been showing works of contem­po­rary art from the collec­tion of the Kunst­mu­seum Basel and the Emanuel Hoff­mann Foun­da­tion since 1980.
