THE LEANING TOWER OF PISA
Pisa, Italy
The Leaning Tower of Pisa is the freestanding bell tower of the cathedral in the Italian city of Pisa. Construction of the tower began on August 8, 1173. Although unconfirmed, this Romanesque style tower may have been designed by Bonanno Pisano. The tower began to sink after construction had progressed to the third floor in 1178 and so construction was halted. In 1360, Tommaso Pisano completed the construction, erecting the belfry and making the last important geometric correction to the structure. In 1990 the tower was leaning 4/100 of inch (1 mm) every week. At this point it was generally thought that the tower would collapse unless something was done. Through the centuries, a number of projects have been implemented to stop the tower’s lean. Finally a British engineering professor came up a solution to prevent the collapse by removing ground soil from under the high side of the tower. Work began in 1999 and it was completed at the beginning of June 2001. In May 2008, after the removal of 70 tons of earth, the tower had been stabilized. The engineers estimated that the tower would be stable for at least 200 years.
The Leaning Tower of Pisa stands at 183.3 feet or 55.8 meters from the ground on the low side and 186 feet or 56.7 meters on the high side.
