Tower of Pisa

Leaning Tower of Pisa is a campanile or bell tower of the cathedral in Pisa, Italy.Tower of Pisa is actually made to stand vertically like a bell tower in general, but began leaning shortly after construction started in August 1173. He was located behind the cathedral and the Campo dei Miracoli third building (ground rainbow) of Pisa.Height of the tower is 55.86 m from ground level and the lowest 56.70 m from the highest ground. Underneath it reaches the wall width 4.09 m and 2.48 m at the top. Its weight is estimated at 14,500 tons. Pisa tower has 294 steps. With the existence of this tower, the economy was growing revenue sector because of the attraction.

Construction of the Tower of Pisa is in three stages within a period of 200 years. Construction of first floor of white marble campanile began on a rocky August 9, 1173, which is an era of prosperity and military glory. The first floor is surrounded by pillars with classical letters, which leads to skewed against arch blinds.
construction of this tower is to put a big clock on the tower. However, some time after construction began, it was 55 meters high tower was deviated from the straight line along the 5 meter. That is why the tower is known as the leaning tower of Pisa. Until now, the efforts of engineers and experts on various countries, the slope of the tower has been repaired to some extent.
After the third floor was built in 1178, the tower began to tilt because the foundation stands on unstable land. Finally, the design of this tower differs significantly from the original plan. This development was also delayed for 100 years because the people of Pisa at that time fighting with people from other regions. But, because that's pending, the tower would be saved. If it is not delayed, maybe even the tower will fall.
At 1198 hours some of the fruit is placed in an unfinished building. About 74 years later, the architect Giovanni di Simone went on to build a tower.
Not long after, the building was again stopped because there is war. Finally, in 1372 so too is the last floor of the bell chamber and the bell was installed there. Development is done by a different architect, that is Tommasso in Andrea Pisano. He successfully combines these elements in a room Gothic style bell with Rome. In the tower there are about seven bells. The biggest bell is installed around 1655.
From this tower, appears unique stories and also makes excited. For example, the astronomer Galileo Galilei had dropped two balls of different weight of the tower. This is to show that the reduced speed of the ball was not because of the weight. But this story also reportedly fairy tale.
However, that right there is the command of the ruler of Italy's Benito Mussolini ordered the tower be returned to a vertical or upright position. To perform it, given the additional concrete tower foundation. Apparently, the results were not as predicted. Added instead of the tower sank into the soft soil.
When World War II, the U.S. military is also nearly destroyed the Tower of Pisa is for fear of snipers there. Fortunately, the withdrawal of troops to save the tower.

There is controversy regarding the identity of the architect of the Leaning Tower of Pisa. Over the past few years predicated designers to Guglielmo and Bonanno Pisano, a prominent local artists in the 12th century Pisa, which is popular by bronze molds, particularly in the Pisa Duomo. Bonanno Pisano left Pisa in 1185 headed to Monreale, Sicily, only to return home and died in his hometown. Sarcophagus was discovered at the base of the tower in 1820.
