Just 15 miles northeast of Pisa and less than 50 west of Florence, Lucca is a must-add to any Tuscan agenda. Its array of wonderfully intact historical sites spans many eras. Lucca’s medieval city walls are, for example, fully intact, and hiking and even biking on top of them is a favorite pastime. The Duomo di San Martino, begun in the 11th century, is another visitor gem, as is the Roman amphitheatre. More recently, Lucca served as the birthplace of Italian opera great Giacomo Puccini.
