Castello di San Giorgio

Castello di San Giorgio is part of Mantua’s Ducal Palace complex. Built for the Gonzaga between 1395 and 1406, it combines defensive architecture with the Camera degli Sposi, Andrea Mantegna’s celebrated frescoed chamber.

Why it matters

Francesco I Gonzaga commissioned the castle from military architect Bartolino da Novara. The fortress was later absorbed into the Gonzaga palace complex, where Luca Fancelli added a courtyard and loggia in the fifteenth century. The Camera degli Sposi, painted by Andrea Mantegna in the northeast tower, is one of the defining works of Renaissance painting. Under Austrian rule, the castle also served as a military zone and prison, including for patriots associated with the Belfiore martyrdom.

What to notice

The roughly square fortress plan, moat, ravelin and four corner towers preserve the castle’s defensive character. Within the complex, the Camera degli Sposi occupies the northeast tower. Other spaces, including the courtyard and loggia associated with Luca Fancelli, reflect the Gonzaga transformation of a fortification into a courtly residence. The former Austrian prison cells preserve another chapter in the building’s history.

Context and history

Construction began in 1395 and was completed in 1406. As the Gonzaga residence expanded, the castle became part of a larger palace complex, connected with adjacent buildings by Giovanni Battista Bertani from 1556. Under Austrian rule, much of the fortress served military and prison functions. The 2012 Emilia earthquakes damaged parts of the complex, including the area of Mantegna’s frescoes; consolidation works preceded the castle’s reopening in 2015.
