20 facts about Leaning Tower of Pisa

Leaning Tower of Pisa
11.In 1284 the building work was again interrupted.
At that time, Pisa suffered a humiliating defeat in a naval battle with Genoa.
12.The tower's construction was resumed in 1319 and extended to the belfry.
It was added around 1350 by Tommaso Pisano. He combined the Gothic elements of the pediment with the Romanesque decoration of the building's main part.
13.The enclosing walls at the base of the tower are 4.09 m long, while the top is 2.48 m long. The staircase inside the bell tower has 251 steps.
The campanile reaches a height of 56,705 m and its deviation from the vertical increases by one millimeter per year.
14.In 1990, Leaning Tower was closed to the public.
In the 19th century, measures were taken to stop the tower's further tilting. However, they did not have the desired effect; the danger was so great that in the early 20th century, the bell tower was closed permanently. A special committee was formed to decide how best to prevent the tower's further tilting.
15.The restoration work took twenty years and in April 2011, the tower was opened to the public.
The restoration work was carried out by a team of experts led by Michele Jemiolkowski, professor of geotechnics at the Polytechnic University of Turin. They applied the method of reinforcing the foundation and preventing further tilting. The Leaning Tower of Pisa is guaranteed by the scientists to last for at least 300 years.
16.The city of Pisa and its Leaning Tower are sometimes called the city of Aries Constellation - La citta dell'ariete.
This nickname dates from ancient times, when the year in Pisa's religious calendar began on March 25 (the day of the Annunciation), rather than nine months later, as in the Gregorian calendar on Christmas Day. March 25 falls in the month of Aries, and the arrangement of all the buildings in Piazza dei Miracoli (Cathedral, Baptistery, and Campanile) resembles the constellation of Aries in shape.
17.The story goes that Galileo used took advantage of the tilt of the tower in 1600 to conduct a scientific experiment regarding the free fall of bodies.
Galileo dropped spheres of different masses from the Leaning Tower and measured their fall time. At the same time, he dropped two balls from the tower: a heavy cannonball with a mass of 8 kg and a lighter musket ball with a mass of 20 g. Both bodies (they had a similar shape) reached the ground at the same moment. He proved that the time of their fall was the same. This proof is one of the foundations of classical mechanics.

However, this event is questioned by some scholars and historians, although no one doubts that Galileo used balls rolling down an incline to study their speed and acceleration.
18.In 1950, Louis Nichilo designed a gold lipstick container in the Leaning Tower's shape.
19.The Leaning Tower of Pisa is the most typical Italian campanile, whose origin many scholars associate with Islamic building influences.
Just as the muezzins from the tops of minarets call the faithful to prayer, the sound of bells from the top of the tower calls Christians to their temples. Other historians claim that it was the adapted towers of Christian churches in Syria that were the first minarets.
20.The Leaning Tower of Pisa is known throughout the world, and for Italians, who hold it particularly dear, it is one of the country's symbols.
