The Cistercian nunnery, founded in 1253 by order of Cardinal Giovanni da Toledo, underwent various alterations during the centuries. The church’s façade in pink and white marble and Gothic rose-window are original 14th century. The church and capitular hall have preserved remains of the original painted decorations. The cloister, deemed to be Perugia’s finest, is attributed to Matteo di Gattapone (1376). In the second floor loggias are displayed some lovely frescoes detached from the refectory walls. It was expropriated and became State property with the unification of Italy in 1861. The district by the same name that joined Santa Giuliana to the town was demolished to make way for the Rocca Paolina (1540-43).
