Leaning Tower of Pisa (Italian: Torre pendente di Pisa) is the bell tower of the Cathedral of the Italian city of Pisa, was supposed to be a tower vertically but began rods forever after building in August 1173 AD shortly. Located next to the Cathedral of Pisa "Square miracles" piazza dei Miracoli.
Tower of Pisa is located in the city of Pisa in Italy mandate of Tuscany, seemed built in 1175 AD, and its construction lasted 174 years, and known as the Leaning Tower of Pisa to the presence of Milan and its deviation from the vertical plane. Consists of eight floors built of white marble Roman-style, up 54.5 meters and has a drawer built into the walls consists of 300 degrees, (currently equipped with a lift).
The tendency is clearly visible where is about 18 feet (inclination more than five degrees), and said that the reason for this inclination is looseness and a decline in soil based upon the tower. The back of this Milan since the early stages of building this tower, but the architects have continued to build on the basis of the same inclination, and in 1275 AD, when they were building the combined fourth and fifth of the tower tried Architects moving center of gravity of the tower in order to avoid AC Milan, but it seems they did not succeed so, and even now taking place attempts to stop the tilt and the establishment of the pillars of dolly. Since 1990, in the last century closed the tower and prevent tourists from climbing because of the collapse of the gallery at every moment. Height of the tower is 55 meters above the ground. The estimated mass of 14,500 tons. The current tendency is estimated at 5.5 degrees, and the tower 294 degrees.
Tower of Pisa has been associated with the world famous Italian Galileo Galilei Galilei and experience for accelerating ground.
Date [edit]
The establishment of the tower began in August 8, 1173 AD. And after the construction of the third floor in 1178, the tower money and stopped construction work of a century. In 1272 AD, was the construction of four additional floors in order to modify the angle of inclination. Business and stopped again in 1301. In the last built in 1372 decks and put the bell in the tower.
There is disagreement about the identity of the architect who built the Leaning Tower of Pisa. For years it was considered the architect Bonanno Pisano, which was built, a renowned artist of the twelfth century of Pisa, famous bronze his works, especially in the Cathedral of Pisa. Construction of the tower, which start in 1174 by Bonanno Pisano, and was completed after a long pause at the hands of Giovanni Pisano was in the second half of the fourteenth century by Tommaso di Andrea Pisano.
Told that the Galileo Galilei dropped two balls (cannon) women with different blocks of the tower to clarify that the speed of their fall does not depend on Ktlhma. This story, although it is on the lips of a pupil of Galileo, is considered wrong broadly.
Benito Mussolini ordered that the tower to be placed horizontal, and was pouring cement foundations. The result was unexpected and made the tower dive more into the soil.
During World War II, the American army has destroyed all the towers in Pisa almost, out of fear of the possibility of snipers in the towers. The bombing was the Tower of Pisa is also planned; but the decision came at the last minute to pull the tower saved from destruction.
In February 27, 1964, asked the Italian government aid to prevent the tower from falling. Was appointed a multilateral group of engineers, mathematicians and historians gathered at the Azores islands to discuss how to install it. After several decades of research and work on the subject, has been closed the tower to visitors in January 1990 after a decade of efforts to patch installation has been re-opened the doors to visitors on December 15, 2001 has been proposed many ways to install the tower, including the addition of 800 metric tons of lead Kthagl high versus the party or from the base of the tower. The ultimate solution to correct the inclination was removing 38 cubic meters of soil from under the party of the high base of the tower. The tower was declared "stable" for the next three hundred years at least. At least two people jumped from the tower using umbrellas (parachute) are Mike McCarthy in the August 5, 1988 and (Boston Globe on August 6, 1988) and Arne Arthus in the February 1, 2000.
