Among the most important monuments of the city is the famous Piazza del Duomo , known as Piazza dei Miracoli, declared a World Heritage Site , with the Cathedral built between 1063 and 1118 in Pisan Romanesque style and the Leaning Tower , a 12th century bell tower , today one of the most famous Italian monuments in the world due to its characteristic inclination.   Seemingly the ‘Must Have’ for any tourist is a picture “holding” the “leaning tower”.
