The Great Tower of Pisa is a free-standing bell tower located in the city of Pisa, in the Italian region of Tuscany. It is one of the most iconic and famous landmarks in the world, and is considered a symbol of the Italian Renaissance. The tower is also known as the Leaning Tower of Pisa, due to its distinctive tilt.
History of the Tower
The Tower of Pisa was built over a period of 199 years, from 1173 to 1372. The tower was initially designed to be perfectly vertical, but the foundation was built on unstable ground, causing the tower to lean. The lean was not noticed until construction was already underway. After this, the construction was stopped for almost a century, until the lean had stabilized. Further construction was then done in an attempt to correct the lean, but it was unsuccessful. The tower was finally completed in 1372.
Architecture of the Tower
The Tower of Pisa is a cylindrical structure, approximately 55 meters (180 feet) tall and made of white marble. It has seven stories, with the bell chamber at the top. The walls are approximately 2.5 meters (8 feet) thick at the base, and 1.2 meters (4 feet) thick at the top. There are 294 steps leading up to the top of the tower.
The Leaning Tower of Pisa
The Tower of Pisa is most famous for its distinctive lean, which is caused by the unstable foundation. The tower currently leans at an angle of 3.99 degrees, and is estimated to be stable for at least another 200 years. In the past, the lean has been as high as 5.5 degrees. To prevent further leaning, the tower is currently undergoing stabilization efforts, which include the installation of steel cables and counterweights.
