Del complesso originario, che la tradizione vuole fondato nel 1222 dallo stesso Santo d’Assisi, rimane in gran parte salvo l’impianto generale, nonostante le distruzioni subite nell’ultima guerra. L’intero organismo, costruito secondo i canoni dell’architettura cistercense, conserva infatti notevoli testimonianze della fase medievale, tra cui il piccolo campanile della chiesa, dalla caratteristica copertura conica. Riedificato nel dopoguerra in modo non conforme all’originale, il complesso è stato adibito a ospedale civile nel periodo compreso fra il 1874 e il 1994.

According to tradition, the original construction was founded by the same St. Francis from Assisi in 1222. Even if it was ruined during the last world war, most of the base plan is in good condition. The whole construction was built according to the rules of the Cistercian style; it still preserves remarkable features of the medieval period as, for example, the small church-steeple with its peculiar conical roof. The complex was rebuilt after the last world war without taking into consideration the original structure and it was used as hospital from 1874.
