The iconic towel in Pisa has become famous worldwide for its tilt, caused by a subsidence of the ground during its construction. In fact, one side of the ground was too soft to support such a weight. Gradually increased, the tilt is now stabilized.
The maximum height of the towel is 56 metres that means 296 steps and 8 floors. These are decorated with rounded -arch as in the Cathedral’s facade, right in front of the Towel. Its function is in fact to be a bell tower for the Cathedral, with 7 bells on its top. They ring for every mass and at midday. Originally, they were confined to a defined function: for example, the justice bell used to ring when a traitor was executed. The towel is definitely the symbol of the city and was also proposed as one of the seven wonders of the modern world.
