Friuli Venezia Giulia is Italy's northeastern frontier — a compact region of extraordinary diversity where the Julian Alps descend to the Adriatic Sea, Roman ruins stand beside Habsburg architecture, and Slavic, Germanic, and Latin cultures blend seamlessly. Trieste is its cosmopolitan capital, a city of caffè culture and literary ghosts; Udine is the elegant Friulian heartland; Aquileia holds one of the ancient world's greatest mosaic floors.
