Clip: Lucca, Italy: Beautifully Preserved

Lucca is still contained within its massive Renaissance ramparts, which locals treat like a circular community park. A 2½-mile path atop the walls is ideal for a loop on foot or by bike. Lacking "must-see sights," Lucca's appeal is its relaxed Old World ambience, elegant streets, and pristine piazzas. San Giovanni Church hosts nightly concerts featuring the music of hometown opera composer Giacomo Puccini. (4½ min)
