The fifth building in my list of the most expiring and outstanding buildings in the world is probably one of the world’s top famous one – The Leaning Tower of Pisa. The name of the building tells almost all the information about reasons for it being so popular. However, very little amount of people know that this tower is about 850 years old, so it is evident that it is leaning a little bit. In fact, the origins of this process are very controversial and discussable. Some architects claim that it was the “interaction” of the architect that it is leaning. Others think that it is the effect of time, which is accused in this process. However, I am just admiring the building and enjoy that I have such an incredible pleasure to watch it falling.
