The Gonzaga family's palace complex is one of the largest in Europe, a labyrinth of about 500 rooms, 15 courtyards, and gardens that evolved over three centuries of dynastic rule. The family began building here in the 14th century and kept adding until the sack of Mantua in 1630, when the Habsburgs auctioned off most of the art collection — what remains is still extraordinary.
The undisputed highlight is the Camera degli Sposi, painted by Andrea Mantegna between 1465 and 1474. The room depicts the Gonzaga court at leisure and ceremony, with remarkable naturalistic portraits of Ludovico Gonzaga, his wife Barbara of Brandenburg, their children, courtiers, and even their dogs. The famous ceiling oculus, painted as if open to the sky, is surrounded by figures peering down — a joke that has startled visitors for 550 years. Book tickets in advance; entry to the Camera is timed and numbers are strictly limited.
Beyond the Camera, the palace contains the Appartamento Ducale, the medieval Castello di San Giorgio, and a collection of Roman and Gonzaga-era sculpture. The Galleria dei Mesi has beautiful zodiac frescos, and the Appartamento di Troia contains painted scenes after Giulio Romano. Allow two to three hours minimum.
