While Venice’s mainland suburb of Mestre has a history and character all its own dating back to medieval times, it owes its growth and fortune to its more powerful offshore neighbor. Unfortunately, it’s everything Venice is not: modern, industrial and cheap. But while they may not compare to the romantic canals of Venice, Mestre does have attractions of its own, including the Torre (Tower) dell'Orologio and the Duomo (Cathedral) di San Lorenzo, located on its town square, Piazza Ferretto.

Poised on the edge of the Venetian lagoon, Jesolo is one of Italy's most popular beach resorts, with millions visiting each year. A favorite with families, Jesolo offers up theme and water parks, an aquarium, and an 8-mile (13-kilometer) golden beach.

Vicenza’s history dates back to pre-Roman times, but it’s a Renaissance figure, Andrea Palladio, with whom the city is most associated. One of the preeminent figures in Western architecture, Palladio built more than twenty buildings here, including the Basilica Palladiana, the Palazzo Chiericati (home to Vicenza’s museum and art gallery), the Teatro Olimpico (his last and some say greatest work) and many other palaces and villas, leading UNESCO to designate the city as a World Heritage Site.

So splendid was medieval Verona that its reputation alone inspired Shakespeare to set two plays here (Romeo and Juliet and The Two Gentlemen of Verona). Though its connection to the actual Capulets is tenuous at best, the so-called Juliet's House draws half a million tourists per year, many of them keen on reenacting the balcony scene. Don't miss the Roman amphitheater and the Palazzo Barberi.

From the brightly painted buildings and fishing boats that line the seafront, to the hilltop baroque church that stands watch over old town—it’s no wonder Rovinj is one of the most-photographed coastal towns along Croatia’s Istrian Peninsula.
