From time to time, we share a random video to fuel your travel dreams. In this clip from my TV episode about Tuscan side trips, I join a friend for a lazy pedal around the top of Lucca’s Renaissance wall. The wide, fortified wall effectively keeps out both traffic and, it seems, the stress of the modern world. Within the wall, which now functions as a circular community park, visitors find a relaxed Old World ambience, elegant streets, and pristine piazzas. | Rick Steves
