 It is overlooked by a fresco in International Gothic style of the "Madonna Enthroned with Child", a Maestà painted by Gentile da Fabriano in 1425.This is the only fresco saved when the stucco altars were added to the nave chapels in the late 16th century.These altars in turn were destroyed in the 19th century and only fragments of the other 14th- and 15th-century frescoes reappeared.
