The buildings of the Ospizio di San Michele were built during the 17th and 18th centuries and served a number of purposes including an orphanage, a hospice for abandoned elderly, and jails for minors and women.
The Chiesa Grande, also known as the San Salvatore degli Invalidi, follows a design (1706) of Carlo Fontana, but construction was completed only in 1834 by Luigi Poletti [REF].
