After breakfast, travel to the nearby city of Pisa. When you arrive, head out on a short orientation walk. Visit the world-famous Leaning Tower. Grab your classic pinching-the-tower photo, then visit the Duomo (Piazza dei Miracoli, once the largest in Europe) and Pisa Baptistry (it's not always possible to climb the tower). The tower was built in the 12th century, but its foundation was on shifting sand and clay, meaning that it now leans at an angle of 4 degrees (after restoration and stabilising work). Then, continue to wander the streets past high-end boutiques, speciality book and antiques stores. After, head back to Lucca, where the rest of the night is free for you to explore at your own pace. Maybe head to a local bar for a Prosecco (or two) and a fresh focaccia with finocchiona salami and pecorino cheese – best enjoyed in the shadow of the Palazzo Pretorio.
