Leaning Tower of Pisa (Italian: Torre pendente di Pisa, La Torre di Pisa)

In the city of Pisa in central Italy, there is a bell tower with simple and elegant shape, which is a model of Romanesque architecture. However, it is far more amazing than that. Every year, 800000 tourists come to the bottom of the tower to express their worries and anxieties about its "slanting but not toppling" body. At the same time, they are very glad that they can witness the miracle caused by its defects. This exciting tower is the famous Leaning Tower of Pisa.

This leaning tower, which can be called a miracle in the history of World Architecture, is not only famous for its "leaning but not toppling", but also because in 1590, Galileo, a great Italian scientist, once made an experiment of free falling motion on the top of the leaning tower. Two iron balls with a weight difference of 10 times fell from the top of the tower at the same time. As a result, the two balls landed at the same time, overthrowing Greece, which had bound people's mind for nearly 2000 years The famous scholar Aristotle's theory that the falling speed of objects with different weights is also different is that "the falling speed of objects is directly proportional to the weight". Galileo created a new era of experimental physics, known as "the father of modern science", and the leaning tower he used to do experiments is also more famous.

Pisa tower is 54.5 meters high and 16 meters in diameter. It is divided into eight layers. Except for the different shapes of the bottom and top layers, the structure of the other six layers is exactly the same. The whole body is made of white marble, surrounded by round columns. It looks like a huge birdcage in the distance. It is said that about the 10th century, the kingdom of Pisa won a battle and plundered a large number of treasures. In order to show off his achievements, the Archduke decided to build a cathedral and build a bell tower next to it. When the clock tower was built to the third floor, it was found to tilt to the South and was forced to stop work. After 1994, Pisa people were determined to build the tower. They asked Pizano, a famous engineer, to measure it repeatedly. It was confirmed that although the tower was inclined, there was no danger of collapse. Then they continued to build it and slightly raised the columns on the south side of each floor. According to the inscriptions on the base of the tower, it was built in 1174 and completed in 1350, which lasted 176 years. However, due to its heavy body and soft geology, the tower still tilts to the south at a rate of 1.25 mm per year. By January 1999, the top of the tower was 4.8 meters away from the central axis. In order to save the leaning tower, Italian authorities have solicited protection plans from all over the world. At the same time, 830 tons of lead blocks have been added to the north side of the tower, and a circle of copper cables have been added to one third of the tower body to pull and fix it to the North. However, slanting has its advantages. More than 100000 visitors come to "slant" every day, throwing a lot of money. If it were a main tower, Pisa would not have today's scenery, and there would not be so much cheap to take.
