The Monastery of SS. Salvatore rises on an area of 11.000 mq and is the largest religious building in town. It was built at the beginning of the 18th century by the architect from Noto, Vincenzo Sinatra. It has two main façades. The eastern façade looks over the open space called “the plain of S. Francesco” and makes it particularly beautiful and attractive. The tower, which is usually believed to have been built on a plan of Gagliardi, due to its waving and delicate decoration, gives and ascending visual effect to this architectural work. The lowest part of the façade shows linear decorations whilst the highest part is characterized by statuesque Borrominian undulations and by Roman Rococo style. The two façades of the monastery contain two rows of beautiful windows; thirteen of them on southern façade, along the main street. These are enclosed by wrought iron gratings. There are five windows on the eastern façade. The second part, also made up of two plains, is scantily decorated and its smooth wall surface. It contains sixty windows, some of which are large, whilst others are small, as well as a series of thin, Doric projections creating a scenario of unusual beauty.
