Information about this place of worship can be traced as far back as 1326, when it adopted the rule of St. Augustine. Later, in the turn of a century and a half, it followed the rule of St. Francis and St. Clare. The latter is depicted together with Saint Lucy in a fresco by Pierantonio Mezzastris that adorns the entrance portico to the structure. To the left of the entrance there is the church of St. Lucy, rebuilt in 1928 on neo-Gothic lines. Inside there are decorations by Vincenzo Turchetti, and on the right altar there is a beautiful statue of St. Lucy attributed to Antonio Calcioni. The wooden choir of the late fifteenth century is noteworthy. The cloister boasts a cycle of frescoes depicting the History of the Passion, unfortunately largely altered by repainting.
