Leaning Tower of Pisa (Italian: Torre di Pisa Pendente) or just the tower of Pisa (La Torre di Pisa) is the bell tower of the cathedral in Pisa, Italy. The tower is located behind the cathedral, and the third is the structure of the Campo dei Miracoli (Miracle) in Pisa.
Although the original plan is built vertically, the tower began leaning to the southeast soon after construction in the year 1173, due to imperfect foundation.
The tower is 55.86 kilometers from ground level to the lowest side and 56.70 m on the upper side. Base width of the building is 4.09 m, a width of 2.48 m. The top of the weight tower is estimated at 14,500 tons and 294 steps.
Construction of the tower of Pisa was built in three phases, which is about 200 years. Construction of white marble on the first floor commenced on 9 August 1173, at the time of military success and prosperity in Italy. The first floor is surrounded by pillars and although some are inclined position, but still held for many centuries.
There is a dispute over the identity of the architect who built the Leaning Tower of Pisa. For years, the design should be made by Guglielmo and Bonanno Pisano, a famous artist in the 12th century, known for his bronze work, particularly in the Pisa Duomo.
Bonanno Pisano left Pisa in 1185 and moved in Monreale, Sicily, and then come back and die in the land of his birth. His tomb was found at the foot of the tower in 1820.
The tower is the first shot after the third floor was built in 1178, with respect to three meters deep amblasnya basis, due to soil movement. This means that the design of the tower is off from the very beginning.
Construction was suspended for almost a century old, as citizens of Pisa almost involved a war with Genoa, Lucca and Florence. During the period of 'rest', the land under the structure stabilized again. And in the year 1198, due to the time when the building was not completed.
Construction was resumed 1272nd The Giovanni di Simone, architect Campo Santo. The fourth floor has been built to compensate for the slope of this tower. Conversion was stopped in 1284, when Pisa won the Genoese in the Battle Meloria.
Construction of the tower was only completed in 1372 stopped. After that, Tommaso Andrea Pisano in the successful completion of the elements of the Gothic tower, with a touch of style in Rome. There are seven bells in the tower, each with an indication of the tone. The largest bell installed in the 1655th.
