Although the original plan was built vertically, the tower began leaning to the southeast soon after the construction in 1173, due to imperfect foundation.
The height of the tower is 55.86 miles from the ground on the lowest side and 56.70 m on the highest side. The width of the base is 4.09 m and the peak width is 2.48 m. Weight of the tower is estimated at 14,500 tons and has 294 steps.
Construction of the Tower of Pisa was built in three stages, which takes about 200 years. Construction of white marble on the first floor began on August 9, 1173, the period of military success and prosperity of Italy. The first floor is surrounded by pillars and although some skew, but still hold for centuries.
There is controversy about the identity of the architect who built the Leaning Tower of Pisa. Over the years, the design was attributed to Guglielmo and Bonanno Pisano, a local artist famous in the 12th century, famous for his bronze casting, particularly in the Pisa Duomo.
Bonanno Pisano left Pisa in 1185 and moved to Monreale, Sicily, but then come back and die in his homeland. His tomb was found at the base of the tower in 1820.
The tower was first tilted after the third floor was built in 1178, due to the collapse of three-meter foundation, due to ground movement. This means that the design of the tower was flawed from the beginning.
Construction halted for almost a century, because the Pisans were almost continually engaged in battles with Genoa, Lucca and Florence. During the period of the 'rest' of this, the ground beneath the structure has stabilized. In 1198, clocks were temporarily installed on the unfinished building it.
In 1272, the building was resumed by Giovanni di Simone, architect of the Camposanto. The fourth floor was built to compensate for the slope of the tower. The rebuilding was stopped in 1284, when the Pisans were defeated by Genoa in the Battle of Meloria.
Construction of the bell tower is not finished stalled until 1372. After that, Tommaso di Andrea Pisano successfully complete the Gothic elements of the tower, with the Romanesque style. There are seven bells in the tower, which respectively represent the notes on the pitch. The biggest bell was installed in 1655. Thank you for reading this article.
