Galleria Civica d'Arte Moderna e Contemporanea
Italy can sometimes feel strangely light on modern art, until you come to Turin. GAM has an astounding 45,000 works in its vaults dedicated to 19th- and 20th-century artists, including De Chirico, Otto Dix and Klee. It cleverly hires art experts to reconfigure its permanent displays on a regular basis. You never know what you're going to get.
