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, and a series of historic rooms and suites: the Nobile Collegio del Cambio, the Nobile Collegio della Mercanzia and the Sala dei Notari.
