Flemish, Spanish and Italian artists feature at Palazzo Bianco, the third of the triumvirate of palazzi that are together known as the Musei di Strada Nuova. Rubens’ Venere e Marte (Venus and Mars) and Van Dyck’s Vertumna e Pomona are among the highlights, which also include works by Hans Memling, Filippino Lippi and Murillo, as well as 15th-century religious icons.
