The Museo Poldi Pezzoli is an art museum near the Teatro alla Scala. It was originated in the 19th century as private collection of Gian Giacomo Poldi Pezzoli and his mother, Rosa Trivulzio, of the family of the condottiero Gian Giacomo Trivulzio. Many of the rooms in the palace were redecorated starting in 1846, a commissions entrusted to Luigi Scrosati and Giuseppe Bertini. Individual rooms were often decorated and furnished to match the paintings hung on the walls. The architect Simone Cantoni rebuilt the palace in its present Neoclassical style with an English-style interior garden. In 1850–1853, Poldi Pezzoli commissioned the architect Giuseppe Balzaretto to refurbish his apartment.
