A Little History of The Leaning Tower of Pisa

It took 3 phases and 177 years to build the Leaning Tower of Pisa. The architect Bonanno Pisano began its construction in 1173 with the first floor which was surrounded by 15 white marble columns with classical capitals and blind arches. With the construction of the third floor in 1178, the tower tilted by 5 cm. to the south-east, due to the unstable subsoil on which it was raised, thus ceasing its construction. This period was very important because it allowed the land to settle, otherwise, the tower would have collapsed.

Giovanni di Simone, 100 years later, resumed work trying to compensate for the inclination of the tower by building four floors vertically, however, the results were not as expected, the bell tower was still inclined and the works stopped again. In 1298 a pluviometric deviation of 1.43 m was measured and 60 years later this figure had increased to 1.63 m. Tommaso Pisano continued the construction of the bell tower finishing the work in 1372. According to Vasari, Nicola Pisano and his son Giovanni have the merit of this work.

The inclination of the tower slowed down in the following centuries, it is believed that its weight is an important factor that allows a certain stabilization of the building. The architect Alessandro Gherardesca made the first restoration in 1835 eliminating the muddy ground and replacing it with a marble base. The result was tremendous and caused a new inclination and in 1918 the deviation of the lead line reached 5.1 m. Until 1990, the slope of the tower continued to increase from 1 to 1.2 mm. per year.
