04. Leaning Tower of Pisa
The Leaning Tower of Pisa is a landmark of Italy just like the Eiffel Tower is the landmark of Paris. It is the main attraction of the Pisa City. The main fame of it is gained from the flaw it has. Work began on the tower in the 1100s, and the sinking, which led to the lean, began by the time the tower reached the third story. Prior to restoration work in the 1990s, it was predicted to topple over by the year 2000. The visitors climb this tower every day to enjoy the great view of the city. The restoration work started in 1990s.
