Location: Italy
Located Tower of Pisa in Italy, Pisa in the state of Tuscany, construction started in 1175 AD, and lasted construction 174 in, known as the Leaning Tower of Pisa to the existence of a tendency by the deviation from the vertical plane, consisting of eight floors built of white marble Roman-style, up 54.5 meters Oppe staircase built within the walls consisting of 300 degrees, (currently equipped with an electric elevator).
Tendency is clearly visible as is about 18 feet (tilt more than five degrees), and said that the reason for this tendency is a looseness and a decrease in soil based upon the tower. The back of this trend since the early stages of building this tower, but the architects continued to build on the basis of the same tendency, and in 1275 AD when they were building a combined fourth and fifth of the tower tried architects move the center of gravity of the tower to avoid the tendency, but it seems they did not succeed so, and even now are attempts to stop the tendency by establishing 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.
Tower of Pisa has been associated the world famous Italian Galileo Galilei Galileo and his experience on the ground speed.
Height of the tower is 55 meters above the ground. The estimated mass to 14.500 tons. The current tendency is estimated at 5.5 degrees, and the tower 294 degrees.
The establishment of the tower began in August 8, 1173 AD. After building the third floor in 1178, Finance tower and stopped the construction work of a century. In 1272 CE, was the construction of four additional floors in order to modify the angle of inclination. Business and stopped again in 1301. And in 1372 built another floor and put the bell in the tower.
