Pisa is an Italian city in Tuscany known above all for its famous leaning tower. Already off axis at its completion in 1372, the 56 m high white marble cylinder is nothing more than the bell tower of the marble Romanesque cathedral that stands nearby, in Piazza dei Miracoli. The square itself hosts the monumental Camposanto and the Baptistery, where non-professional singers test themselves every day with its famous acoustics.

The tower of Pisa is the bell tower of the cathedral of Santa Maria Assunta, in the famous Piazza del Duomo, of which it is the most famous monument because of the characteristic slope, symbol of Pisa and among the iconic symbols of Italy.

With a mass of 14,453 tons, the curved line predominates, with rounds of blind arches and six floors of loggias. The slope is due to a subsidence of the underlying land that occurred already in the early stages of construction. The inclination of the building measures 3.9 ° with respect to the vertical axis.
