Rocca Sanvitale, Fontanellato

It is prototypical of the urban castle-houses of the turbulent medieval communes of Northern Italy.

The crenelated walls and asymmetric towers are surrounded by an arcaded town.

The optical chamber (camera ottica) has an optical system that projects to an inside wall a view of the town through mirrors and a prism.

Inside are the frescoes of Diane and Acteon painted in 1523–24 by Parmigianino for the Count Galeazzo Sanvitale and his wife, Paola Gonzaga.
