Palazzo Valenti Gonzaga, Museum of modern art in Mantua, Italy

Palazzo Valenti Gonzaga is an art museum in Mantua housing modern collections within historic rooms. The spaces feature original 17th-century frescoes and stone wall carvings depicting various noble families.

The Valenti Gonzaga marquises lived here from the 16th century. In 1670 the Flemish architect Frans Geffels restructured the building in Baroque style, while the facade is by Nicolò Sebregondi (1585–1652), who also built Villa La Favorita. Cardinal Silvio Valenti Gonzaga, art collector, was born here. After the family's decline the palazzo stood abandoned until a radical restoration in the 1990s.

The palazzo was home to the Valenti Gonzaga marquises from the 16th century, and Silvio Valenti Gonzaga, later a cardinal and art collector, was born here; his great-nephew Luigi also became a cardinal. On the piano nobile the Galleria Museo Valenti Gonzaga displays Flemish painter Frans Geffels's frescoes, eighteen statues attributed to Giovanni Battista Barberini and a collection of old and rare books.

The palazzo stands at Via Pietro Frattini 7, and the museum galleries occupy the piano nobile, the finely frescoed upper floor, so plan to climb or take the stairs to reach them. The Casa della Beata Osanna Andreasi, a 15th-century house now used as a museum, is immediately to the left of the building. Allow time for both permanent and temporary exhibitions.

The piano nobile holds eighteen statues attributed to Giovanni Battista Barberini (1625–1691), a sculptor from Como, alongside a collection of old and rare books. The adjoining Casa della Beata Osanna Andreasi, a 15th-century building now a museum, stands to the left of the palazzo.
