Lucca is one of Tuscany’s undiscovered gems. The city is encircled by an impressive, well-preserved Renaissance wall and dotted with churches, including the Duomo, an imposing Gothic cathedral. There’s a lively student atmosphere, thanks to the University of Lucca, and a good selection of restaurants and bars. The lively San Frediano district is a great place to wander, with its narrow streets, artisan shops and outdoor cafes. Don’t miss the Guinigi Tower, with its unique tree-shaped roof, or the Museo Nazionale di San Matteo, home to a vast collection of religious art.
