Lording it over Piazza IV Novembre is Perugia's stark medieval cathedral. A church has stood here since the 900s, but the version you see today was begun in 1345 from designs created by Fra Bevignate. Building continued until 1587, although the main facade was never completed. Inside you'll find dramatic late-Gothic architecture, an altarpiece by Signorelli and sculptures by Duccio. The steps in front of the facade are where seemingly all of Perugia congregates; they overlook the pink-and-white Fontana Maggiore.
