Why does the Leaning Tower of Pisa lean? The Leaning Tower of Pisa is actually a bell tower behind the Pisa’s Cathedral. It is one of the oldest buildings of the Cathedral Square. It is nearly 56 meters high (the lower side) and nearly 58 meters high (the higher side). The tower was being constructed during the period of hundred and seventy-seven years. The construction period was divided into three stages. First floor works began in 1173. This was the time of military power and general welfare.
The Tower of Pisa started to lean after a short time. They were starting the third floor works when it suddenly started to sink. It happened in 1178. The main cause to this was the soil that was not firm enough. In the late 1200s, the construction works were close to end. The upper floors were built with one side lower, in order to make a kind of balance. This made the tower rather curvy than leaning, but it looks like it is leaning when observed from the outside.
By the beginning of the fourteenth century, the seventh floor was finished. The tower has seven bells and eight stories. By the end of the fourteenth century, the bell chamber was made as well. In 1990s the authorities decided to strengthen the Tower of Pisa. There has been a lot of damage through out the ages, so was necessary to fix it. The materials have wasted due to time, rain and wind. The color of the material has changed in some parts. In 2001, reparation works were finished and the tower was again open to the visitors. Only thirty people can enter the Tower of Pisa in a group accompanied by a guide. The visit to the tower lasts little more than thirty minutes. It is not allowed to bring any of your things inside (like purses, for example). You can only carry your camera. If you have problems with dizziness, maybe you should not visit the tower.
Regardless of the state that the tower was in during the 1990s (and before) – it has always been an attraction. Nearly every post card you buy as a souvenir in Italy has at least one picture of the Tower of Pisa on it. This building is a kind of Italian trademark. Who ever comes to Italy, whether for business or pleasure, goes to see the tower.
