3. Tower of Pisa
The Leaning Tower of Pisa is a building on the square of miracles in Pisa, Italy. The Leaning Tower of Pisa was started in 1173 and completed in 1399. The tower is 60 meters long, approximately 10 degrees tilted. Therefore, the tower is 56.67 meters high and the low part is 55.86 meters long. The tower is inclined because the structure is covered with water.
This major problem was understood after construction started. When the first floor of the tower was completed, it was noticed that the tower began to bend. However, as it was too late, construction continued with great difficulty. Tourists from all over the world come to Italy to see the Leaning Tower of Pisa.
