Perugia's money exchange in medieval times, the extravagantly adorned Nobile Collegio del Cambio has three rooms: the Sala dei Legisti (Legist Chamber), with 17th-century wooden stalls carved by Giampiero Zuccari; the Sala dell’Udienza (Audience Chamber), with outstanding Renaissance frescoes by Perugino; and the Chapel of San Giovanni Battista, painted by a student of Perugino’s, Giannicola di Paolo.
