Flanking Corso Vannucci, this Gothic palace, constructed between the 13th and 14th centuries, is architecturally striking with its tripartite windows, ornamental portal and fortress-like crenellations. It was formerly the headquarters of the local magistracy, but now houses the city's main art gallery, the Galleria Nazionale dell'Umbria. Also of note is the Nobile Collegio del Cambio , Perugia's medieval money exchange, with its Perugino frescoes.
The extravagantly adorned money exchange 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. Nearby sits the Nobile Collegio della Mercanzia , showcasing a 14th-century audience chamber with exquisite wood panelling.
The Sala dei Notari was built from 1293 to 1297 and is where the nobility met. The arches supporting the vaults are Romanesque, covered with frescoes depicting biblical scenes and Aesop's fables. To reach the hall, walk up the steps from Piazza IV Novembre.
