This monument is that, among other things, “Piazza dei Miracoli” the imagination of each of the old to the young people awake. First, we give you some information and events in its long history.
Began construction of the imposing mass during the year 1174 by Bonanno Pisano. When the tower had reached the third floor renovation, as it began to sink into the ground. The tower remained for 90 years. It was completed by Giovanni Simone Simone them Tommano (son of Andreo Pisano), awarded the bell tower in the middle of the 14th century.

This work is very famous Romanesque style, and as mentioned date of 1174. Cylindrical shape is available, Pentecost open galleries. The cornice separates the galleries, one of the other and provides a series of small arches built in the capitals of the slender columns. Based on a series of large arches geometric decorations. In the belfry are the project, although the base of the arches, the difference is, instead of the reduced portion, the watch case.
While impressive, the monument to the elegance and lightness due to arcades and open galleries from one store to another.

Unfortunately, today, the mass sink very slowly. The issue of about 1 mm. per year. Because no one can say that sank in the face of mathematics in the future, the annual fee, without stopping, three measures have adequate resources, based on scientific studies and proposed projects. However, the orientations of high precision instruments continuously.
