This important museum is housed in the Renaissance Ratzé Mansion and, incongruously, an old slaughterhouse connected to the mansion proper by an underground passage. The mansion displays 12th- to 19th-century art, including several works by Hans Fries. The 19th-century slaughterhouse, a stark stone structure modernized with steel-and-glass blocks, provides the setting for a provocative mix of sacred sculptures and the kinetic, scrap-iron whimsies of native son Jean Tinguely. The attic gallery displays 19th- and 20th-century paintings from Swiss artists, as well as from Delacroix, Courbet, and others. Take a breather in the quiet sculpture garden overlooking the river. Limited descriptive material in English is available upon request, and guided tours in English can be booked in advance.
