Located north of Siena, Pisa is famous for its Leaning Tower, a free-standing campanile or bell tower. Closed to the public since 1990, the tower has now reopened following a lengthy restoration project to reduce its tilt. Next to the tower, on Campo dei Miracoli, stand the elegant 11th-century Gothic Cathedral and the Baptistry. Nearby, the 13th-century Camposanto is a cemetery contained within a unique collonaded courtyard, said to have been built to enclose earth brought from Jerusalem by the Crusaders.
