Orvieto, Umbria, Italy, during a late spring sunset. Orvieto is noted for its Gothic cathedral, or duomo. The church is striped in white travertine and greenish-black basalt in narrow bands; its design has often been attributed to Arnolfo di Cambio, but the prevailing modern opinion is that its master mason was an obscure monk named Fra' Bevignate from Perugia; construction began in 1290.
