Italy is known for its unique architectural wonders. Out of the many, The Leaning Tower of Pisa, located in the city of Pisa, is the most popular one and has its replicas in almost all parts of the world. The history of this architectural beauty goes back to 1173, when this 185 feet long tower made up of white marbles was built with some constructional error. The tilt was observed after several years, and then the name came into existence. Currently, it is tilted 4.5 meters from the perpendicular.
