The Tower Of Pisa was built August 9th 1173. In Italian it is called Torre De Pisa. The Tower of Pisa leans because the soft ground cannot handle the weight of the tower. The Tower Of Pisa generates over 21,000,000€ per year. The Italian government also invested lots of money on renovating the tower. The tower was utilized for bells and christian churches. The Tower Of Pisa is 60 Meters tall, and has 8 floors. I think The Tower Of Pisa is a unique place.
