Church of Sant'Orsola

The Church of Sant'Orsola in Mantua, Italy, was designed and built in 1608 by Antonio Maria Viani, the architect of the ducal court of the House of Gonzaga. The church was commissioned by Margherita Gonzaga d'Este, the widow of Alfonso II d'Este. Margherita, while not a nun herself, as a widow came to live in an apartment in the Clarissan monastery that was once adjacent.

The octagonal church was decorated by major regional artists including Domenico Fetti and his sister Lucrina, Lodovico Carracci, Carlo Bonomi, and Antonio Maria Viani. After suppression of the convent in the 1780s, the convent had become a hospital.
