In 1996, a room which the nuns were using for their ironing was found to have spectacular 13th century frescoes on the walls under whitewash applied when the palace became part of the orphanage in the 16th century. These were restored by 2006. This chamber is considered to have functioned as the primary reception room of the Cardinal Palace, and was also the location of a court of law. The work is tentatively ascribed to the so-called Third Master of Anagni, and to be of the 1240's. The frescoes turned out to be the most important cycle of medieval secular paintings to have survived in Rome.
