AMAZING FACTS

Leaning Tower of Pisa is a bell tower at Pisa, Italy. It is famous for leaning 4.4 meters out of line when measured from the seventh story. It was built to stand vertically but began leaning soon after construction started in August 1173. It tilts because its foundation was built on unstable soil. The ground beneath the tower first started to sink after the first three stories were built. The height of the tower is 55 meters from the ground. The construction of the building began in 1173 and lasted two centuries.



The leaning tower of Pisa was commenced in 1152, and was not finished till the fourteenth century. Tho cathedral to which this belongs was erected to celebrate a triumph of the Pisans in the harbor of Palermo in 1063, when allied with the Normans to drive the Saracens out of Sicily. It is a circular building, one hundred feet in diameter and 179 feet in extreme height, and has fine mosaic pavements, elaborately carved columns, and numerous bas-reliefs. The building is of white marble. The tower is divided into eight stories, each having an outside gallery of seven feet projection, and the topmost story overhangs the base about sixteen feet, though, as the center of gravity is still ten feet within the base, the building is perfectly safe.




It has been supposed that this inclination was intentional, but the opinion that the foundation has sunk is no doubt correct. It is most likely that the defective foundation became perceptible before the tower had reached one-half its height, as at that elevation the unequal length of the columns exhibits an endeavor to restore the perpendicular, and at about the same place the walls are strengthened with iron bars.
