Leaning tower of Pisa
The leaning Tower of Pisa is famous
because it leans. Although it was designed to be perfectly vertical it started
to lean during constructions. However, even without this famous characteristic
this building would still be on e of the most remarkable architectural
structures. It stands at 60 metres at about 10 degree angle.
Tower of Pisa is more accurately reffered
to simply as the bell tower. The Pisa
tower is one of the four buildings that make up the cathedral complex in Pisa,
Italy, called Camp dei Miracoli , which means Field of Miracles.
The leaning Tower of Pisa is the crowning
glory. Although only a third as high as the Washington Monument, it was a
miracle of engineering with 207 columns ranged around eight stories.
The construction of Tower of Pisa began in
August 1173 and continued for about 200 years due to a series of war. Until
today, the name of the architect is a mystery. The leaning Tower of Pisa was
designed as a circular bell tower that would stand 185 feet high. It is
constructed of white marble. The tower has eight stories, including the chamber
for the bells. The bottom story consists of 15 marble arches. Each of the next
six stories contains 30 arches that surround the tower. The final story is the
bell chamber itself, which has 16 arches. There is a 297 step stpiral staircase
inside the tower leading to the top.
The top of the leaning tower of Pisa is
about 17 feet off the vertical. The tower is also slightly curved from attempts
by various architects to keep it from leaning more or falling over.
Many ideas have been suggested to
straighten the Tower of Pisa, including taking it apart stone by stone and
rebuilding it at different location. In the 1920’s the foundations of the tower
were injected with cement grouting that has stabilized the tower to some
extent.
Until recent years tourists were not
allowed to climb the staircase inside the tower, due to consolidation work. But
now the leaning Tower of Pisa is open again and it is one of the wonders of the
great architect in the world.
