Interesting facts on Leaning Tower of Pisa, Italy

1. The Leaning Tower of Pisa is a campanile or a freestanding bell tower located behind the cathedral in the city of Pisa, region of Tuscany in Italy.

2. The height of the tower is 55.86 meters (183 ft.) on the low side and 56.70 meters (186 ft) on the high side, and it has seven floors and an observation deck at the top.

3. It weights approximately 14,500 metric tons (16,000 short tons)

4. The architect is credited as being Bonanno Pisano and he laid the foundation of the tower in August 1173.

5. Unfortunately, the three meter foundation was flawed from the beginning because it was laid in weak, unstable subsoil. The tilt began during construction because the ground was too soft on one side to properly support the weight of the tower.

6, The tilt of the tower increased over time before it was completed. And, it gradually increased until the tower was stabilized and the tilt partially corrected in the 20th and 21st centuries.

7. The tower has a total of 296 steps to the top and the seventh floor has two fewer steps on the north side facing staircase because of the tilt.

8. Before restoration in the 1990s and 2000s the tower leaned at a 5.5 degree angle.

9. Today the tower leans at approximately 3.99 degrees. The top of the tower is displaced horizontally 3.1 meters (12 ft 10 in) from where it should be if the structure were perfectly vertical.

10. Construction took place over three phases and 344 years. It is constructed of marble and the ground floor is a blind arcade with engaged columns with classical Corinthian capitals. Each phase of construction was interrupted by wars in which the city-state of Pisa was involved.

11. The second phase of construction continued in 1272. The architect now was Giovani di Simone, also architect of the Campasanto. He built the upper floors with one side taller than the other. Therefore, the tower is actually curved.

12. The third phase of construction continued in 1319. The seventh floor was built by architect Tommaso di Andrea Pisano. He brought together the Gothic elements of the bell-chamber with the Romanesque style of the tower.

13. There are seven bells in the tower. Each bell is one note of the musical major scale.
