The Poldi Pezzoli home and museum is known throughout the world, and is the brainchild of aristocratic Milanese collector Gian Giacomo Poldi Pezzoli (1822-1879). Open to the public since 1881, it houses paintings by grand masters such as Mantegna, Piero della Francesca, Botticelli, Raffaello and Tiepolo, as well as important decorative arts collections featuring arms and armor, glass, ceramics, gold, solar and mechanical clocks, fabrics and furniture. Besides the alluring 19th-century rooms, also worth a visit are the arms room, designed by contemporary artist Arnaldo Pomodoro (2000), the recently added gold room (2006) and the new collector’s room, which periodically hosts private Milanese and Lombardian collections.
