| The Leaning Tower of Pisa |
By Dominic Siano
Regarded widely as one of the greatest wonders of the world, the
Leaning Tower of Pisa is situated in the city of Pisa, Italy. Italy has
an important place in the history of the world, and the Leaning Tower of Pisa
just adds more to the country's rich history. The Leaning Tower of Pisa was
originally built as a marble campanile, or bell tower, for Pisa's cathedral,
located in the 'Campo dei Miracoli'.

The Tower was given such a name because it does not stand erect like other
towers, but 'leans' at an angle of 5.5 degrees from the perpendicular. This
is because the uneven settling of its foundation.The height of the Leaning
Tower of Pisa is 55 meters from the ground while its weight is estimated at
14,453 tons. The Leaning Tower of Pisa has 296 steps.
The history of the Leaning Tower of Pisa is interesting as well. It
took centuries to construct the Leaning Tower of Pisa. The construction began
on August 9, 1173, and went on for two centuries. The third floor of the Leaning
Tower of Pisa was constructed in 1178 when it began to lean, and thereafter
the construction stopped. Four more floors were constructed in 1272 to make-up
for the inclination. The construction stopped again until 1372 when the last
floor of the Leaning Tower of Pisa was built. In the same year, the bell was
finally installed.
The Leaning Tower of Pisa holds a significant place in the world history as well.
Famous physician Galileo Galilei once dropped two cannon balls of different masses
from the Leaning Tower of Pisa to demonstrate their speed of descent was independent
of their mass. After some years, Italian dictator Benito Mussolini commanded the
Tower to be erected. So cement was poured into its foundation but the consequences
were disappointing as the Leaning Tower of Pisa sank further into the soft soil.
Reflecting more on the history of the Leaning Tower of Pisa, it would be interesting
to know that during World War II, the American forces were ordered to demolish all
the towers in the city of Pisa because of the threat of snipers in the city. All
the towers were demolished except the Leaning Tower of Pisa because of a last-minute
order to retreat.
In 1990, the Leaning Tower of Pisa was closed as there was a threat of collapse.
This was because it was subsiding at the rate of 0.03 inches a year. Engineers
undertook a strengthening project that decreased the lean by 17 inches to about
13.5 ft. The work was completed in May 2001 and reopened for public in June 16, 2001.
The Leaning Tower of Pisa may be leaning because of a blunder committed by
12th century engineers, but it is still one of the most famous structures
known across the world and will always remains so.
