Located in Pisa, the Leaning Tower of Pisa in Italy has become the sign of Italy. It is the third oldest structure in Pisa’s Cathedral Square. There are eight floors in the Leaning Tower of Pisa including observation deck at the top. The weight of the tower is about 14,500 metric tons. There are amazing facts of the Leaning Tower of Pisa that we will mention here.
The Leaning Tower of Pisa was not originally intended to lean, but because it was built on soft soils the tower gradually leaned to one side. Prior to its restoration (修复) from 1990 to 2001, the tower had a tilt (倾斜) of 5.5 degrees. Many people think that it will fall one day. Millions of tourists come to the lawns around the tower to take the classic photo pretending to hold up or knock down the tower.
It is said that you must visit the Leaning Tower of Pisa during the day. At night the shops are closed and it appears unimpressive. But, if you plan to visit on a full moon night, the tower will look charming. Mornings are the best time to beat the crowds. Summer in Pisa is very hot and wet, but you can expect rain in fall and winter.
Even though some people regard the tower to be an engineering failure owing to the tilt, the tower has acquired a special place in history. The tower has also been used for experiments by the famous Italian scientist named Galileo Galilei. He is believed to have thrown two balls of different mass from the tower to prove that their falling time is not related to their mass.
