Poldi Pezzoli Museum (Museo Poldi Pezzoli)

Housed in the 17th-century palace that was once the Pezzoli family residence, this house-museum contains one of Milan's most prestigious collections. It’s a treasure trove of paintings by Botticelli, Bellini, and Mantegna, as well as decorative art, armor, and ancient artifacts accrued by Gian Giacomo Poldi Pezzoli in the 19th century.
