The Leaning Tower of Pisa is in the news. But it isn't the real leaning tower - it is another of Italy's leaning towers. This one is in Bologna. It is the Garisenda tower. It is moving more than usual.
The Medieval Towers in Italy came about because they stood as a symbol of a clan's power and influence. The higher the better. Pisa is the most famous of all their leaning towers. But there are, in fact, 10 leaning towers in the whole of Italy, mostly in Venice and Pisa.
Typically, it is the "weak, unstable soil" that is the "reason" for the towers' leanings. Another cited reason is "the yielding of the ground". A number of them started tilting from the beginning of their construction.
You can see pictures of all the towers in this article HERE. Did you know that because Pisa started to lean as the tower was being made. The builders decided to compensate for the tilt by building floors with one side taller than the other. The Tower took two centuries of elapsed time to build - allowing for the underlying soil to settle. It was started in 1173, then stopped, resumed in 1271, then stopped, and finally resumed in 1360. This Tower is known as the site where Galileo Galilei carried out his experiments to prove the Laws of Gravitation.
Do you want to see a modern leaning tower? It is the 524.9-foot Capital Gate also known as the "Leaning Tower of Abu Dhabi." The building inclines 18 degrees westwards — more than four times the lean of the Tower of Pisa. Capital Gate also holds the Guinness World Record for the farthest manmade leaning building.That's more than 4 times the Tower of Pisa. It has been "built to lean."
Our CN Tower looks like an arrow launching to Heaven.
