Bologna

Fusing haughty elegance with down-to-earth grit in one beautifully colonnaded medieval grid, Bologna is a city of two intriguing halves. One side is a hard-working, high-tech city located in the super-rich Po valley where suave opera-goers waltz out of regal theatres and into some of the nation's finest restaurants. The other is a bolshie, politically edgy city that hosts the world's oldest university and is famous for its graffiti-embellished piazzas filled with mildly inebriated students swapping Gothic fashion tips.
