Bonnano Pisano, the engineer in charge, sought to compensate for the lean by making the new stories slightly taller on the short side, but the extra masonry caused the structure to sink still further. Work was suspended several times as engineers sought solutions, but the tower was ultimately topped out in the 14th century, still leaning.

Originally built as a bell tower.

Bonnano Pisano was the engineer in charge.

The purpose : The Tower is the free-standing bell tower or "campanile" of the Duomo (Cathedral). It is the third structure in Pisa's "Campo dei Miracoli" ("Field of Miracles"), besides the Duomo, the Baptistery and the Camposanto (cemetery).

The Tower of Pisa.The Leaning Tower of Pisa (Italian: Torre pendente di Pisa) or simply The Tower of Pisa (La Torre di Pisa) is the campanile, or freestanding bell tower, of the cathedral of the Italian city of Pisa. It is situated behind the Cathedral and it is the third structure in Pisa's Campo dei Miracoli (field of Miracles).

Although intended to stand vertically, the tower began leaning to the southeast soon after the onset of construction in 1173 due to a poorly laid foundation and loose substrate that has allowed the foundation to shift.

The height of the tower is 55.86 m (183.27 ft) from the ground on the lowest side and 56.70 m (186.02 ft) on the highest side. The width of the walls at the base is 4.09 m (13.42 ft) and at the top 2.48 m (8.14 ft). Its weight is estimated at 14,500 tonnes. The tower has 294 steps. [1]

Construction
The Tower of Pisa was a work of art, performed in three stages over a period of about 174 years. Construction of the first floor of the white marble campanile began on August 9, 1173, a period of military success and prosperity. This first floor is surrounded by pillars with classical capitals, leaning against blind arches. Today, it is still unscarred from centuries of weather and age.[citation needed]


History
Galileo Galilei is said to have dropped two cannon balls of different masses from the tower to demonstrate that their descending speed was independent of their mass. Many parts of this story, though reported by Galileo's own student, are widely considered to be merely legendary. While Galileo probably did climb to the top of the tower and drop two items to further prove his already-proven theory, more than likely, the items were not two cannonballs.[citation needed]

Benito Mussolini ordered that the tower be returned to a vertical position, so concrete was poured into its foundation. However, the result was that the tower actually sank further into the soil.[citation needed]

During World War II, the Allies discovered that the Nazis were using it as an observation post. A humble U.S. Army sergeant was briefly entrusted with the fate of the tower. His decision not to call in an artillery strike saved the edifice.[2]

On February 27, 1964, the government of Italy requested aid in preventing the tower from toppling. It was however considered important to retain the current tilt, due to the vital role that this element played in promoting the tourism industry of Pisa.[3] A multinational task force of engineers, mathematicians and historians was assigned and met on the Azores islands to discuss stabilization methods. After over two decades of work on the subject, the tower was closed to the public in January 1990. While the tower was closed, the bells were removed to relieve some weight, and cables were cinched around the third level and anchored several hundred meters away. Apartments and houses in the path of the tower were vacated for safety. After a decade of corrective reconstruction and stabilization efforts, the tower was reopened to the public on December 15, 2001. It was found that the lean was increasing due to the stonework expanding and contracting each day due to the heat of sunlight. This was working in combination with the softer foundations on the lower side. Many methods were proposed to stabilize the tower, including the addition of 800 metric tons of lead counterweights to the raised end of the base.[citation needed] The final solution to prevent the collapse of the tower was to slightly straighten the tower to a safer angle, by removing 38 m3 of soil from underneath the raised end. The tower has been declared stable for at least another 300 years.[citation needed]

In 1987, the tower was declared as part of the Campo dei Miracoli UNESCO World Heritage Site along with neighbouring cathedral, baptistery and cemetery.[citation needed]
