According to the monitoring group led by Salvatore Settis, Carlo Vigiani and Donato Sabia, the tower has lost 4 cm of its tilt over the past 20 years, and its health is better than predicted by an international committee coordinated by Jamiolkowski between 1993 and 2001. Is. , who planned and coordinated the consolidation work.
The non-profit Opera della Primaziale Pisana provides funding for the group’s activities, which include monitoring the tower, enhancing conservation efforts, and furthering academic study of the structure. According to at least one Italian authority, modern engineering will eventually cause the tower to straighten out.
Leaning Tower of Pisa Engineering
The Leaning Tower of Pisa is 55.86 meters high, weighs 14,700 tonnes, and extends 3.9 meters vertically with an inclination of approximately 4°. The Italian government requested assistance in 1964 to stop the Leaning Tower of Pisa from collapsing.
In 1173, the architect Bonanno Pisano began work on the first level, which was surrounded by 15 white marble columns with classic capitals and blind arches. Due to the unstable subsoil on which the tower was built, the tower leaned 2 inches (5 cm) to the southeast during the construction of the third level in 1178, ending its construction. This period was crucial as it allowed the ground to freeze, without which the tower would have collapsed.
