The Dominican community of White Brothers was founded outside the city walls in 1225. Construction of this monastery began in 1301 and continued through the 16th century. Most of it has a bland façade. The exception is this elegant southern portal with its Gothic arch and a carving of St. Dominic in the lunette. This entrance to the church was built from the design of Bonino of Milan around 1419. While you are at the northeast section of town, it is worth touring the Cloister of the Dominicans plus the Monastery Museum and Library.
