The 14th century convent church of Santo Stefano has two cloisters. The biggest and most significant was largely rebuilt following a fire in 1529.
The smaller cloister, only partially affected by the fire, retains its fourteenth century Gothic style, with original columns and rosette capitals.
Following the Napoleonic suppression of the early 1800s, the monastery buildings fell into decline, and are now the headquarters of the Ministero della Finanza (Revenue Agency).
