The church of San Salvatore in Ognissanti was established during the thirteenth century by the Umiliated friars, a religious request that was dedicated to the exchange and processing of fleece, misusing the course of the Arno and Mugnone which streamed here. During the fourteenth century the church was advanced with works of craft of phenomenal worth, such as Giotto's Maestà. Subsequently, the complex passed to the Observant Friars and significant renovations were started. The inside, while holding the Gothic engineering with a single nave and raised transept, has a sober Baroque beautification, so the exterior implicit 1637 on a task by draftsman Matteo Nigetti.
