The Leaning Tower of Pisa or in Italian Torre Pendente di Pisa is one of the most popular and photographed attractions in Europe. It is located next to the Cathedral of Pisa, in Piazza dei Miracoli in the Tuscany region of Italy. The tower stands at a height of 55.9 meters from the ground and consists of 297 steps and 207 columns. The famous landmark is part of UNESCO World Heritage Site Piazza del Duomo.
While it could be just another tower in Italy, the reason it has become so popular is due to the fact that it leans sideways at a four degree angle in present day due to the soft ground underneath it that has been unable to support the structure (and up until the year 1990, it leaned at a ten degree angle).
The construction of the tower began in year 1173 by architect Bonanno Pisano, and was completed until 1372 due to the many wars that occurred within this period.
It is said that Galileo Galilei conducted an experiment here in order to prove that the mass of an object did not affect its speed. For this, he dropped two different sized cannonballs from the tower.
The tower has been leaning for over 800 years and it is hard to believe it will not fall over one day. While the original intention was for it to stand vertically, but it began leaning and sinking into the ground since its construction began and it has been in danger of collapsing ever since. Efforts to keep it existing have been made for decades and it has been suggested to destroy it and reconstruct it brick by brick at a different location.
For many decades, visitors were not allowed to go inside for conservation and safety reasons. However, up until recently, tourists can enter and explore the stories that make up this iconic landmark of Italy.
