It took over 800 years to finish all the building works. Many generations of engineers took efforts to straighten the tower but in vain.

Now the Leaning Tower has seven bells and eight floors. Its maximum height is 55.86 meters. There are 294 steps to its top.

Every year the Tower of Pisa attracts millions of tourists and thousands of scientists. But most of them admire the structure from outside because of entrance restrictions. Only thirty people are allowed to stay inside at a time.
