In this museum dedicated to 20th century art, perhaps the most famous piece is Giuseppe Pellizza da Volpedo’s seminal “The Fourth Estate” (1901), a symbol-laden painting of a labor strike march, which hangs in the passageway outside the museum, free for all to admire. Inside, a circular concrete passageway winds up to the museum entrance on the third floor. The collection showcases Italian art from Futurist to the Arte Povera movement, trying to make the case that Italy’s contribution to the world of art did not end at the Renaissance. While that claim is only partially successful, you will see some brilliant bursts of genius like the magnificent “Philosopher’s Troubles” (1926) by Giorgio de Chirico and the moving “Thirst” (1934) by sculptor Arturo Martini. One of the best things about this museum? The views of the Duomo and its piazza down below.
