Leaning Tower of Pisa

Leaning Tower of Pisa

Leaning Tower of Pisa

Bonnano Pisano, an Italian engineer, began to work on a bell tower for the cathedral in Pisa in 1174. Today the tower has become a famous tourist attraction and one of the most famous structures in the world. It became famous because of a mistake.
Three stories were built and the tower began to lean. The soil was soft and the thick foundation was not strong enough to support its weight. Construction was stopped for almost a hundred years and in 1275 it began again. The tower was finally finished in the 14th century, but each year it leans 1.25 millimeters.
In 1934, the Italian government pumped concrete under the base to try to correct the leaning, but the leaning increased.
The great astronomer, mathematician and physicist Galileo was born in Pisa. He made some of his experiments concerning the speed of falling objects from the Leaning Tower of Pisa.
