Tower of Pisa - Historical
WHEN was the leaning Tower of Pisa
The construction of the leaning tower of
Pisa began in august 1173, but was
interrupted several times by wars, debt and while engineers
worked on solutions to correct the lean.
We now know that without these interruptions
that allowed the soil to compress under the tower, it would
have certainly toppled over.
Pisa Tower was eventually completed in the
WHY was the leaning Tower
of Pisa built?
The purpose of Tower of Pisa was a touristic one from
the beginning. The city of Pisa was at the beginning a simple Italian seaport.
Its fame and power grew gradually over the years, as the people of Pisa were
involved in various military conflicts and trade agreements.
The Pisans attacked the city of Palermo on the island of Sicily in 1063. The
attack was successful and the conquerors returned to Pisa with a great deal of treasure.
To show the world just how important the city was, the people of Pisa decided to
build a great cathedral complex, the Field of Miracles. The plan included a cathedral, a
baptistery, a bell tower (Tower of Pisa) and a cemetery.
WHO built the leaning tower of Pisa?
The real identity of Tower of Pisa’s
architects is a mystery.
The most accredited architects of this first
phase of work are Bonanno Pisano and Gherardo din Gherardo.
The second phase of construction started in
1275, and the work is attributed to Giovani di Simone. Tommaso
Pisano (1350-1372) was the architect who finished the work.
WHY does the Tower of Pisa
The leaning of the Tower of Pisa comes into
the story in 1173, when construction began.
Thanks to the soft ground, it had begun to lean by the time its builders got to
the third story, in 1178. Shifting soil had destabilized the tower's foundations.
Over the next 800 years, it became clear the
55-metre tower wasn't just learning but was actually falling at a rate of one to two
millimetres per year.
Today, the Leaning Tower of Pisa is more than five metres off perpendicular.
Its architect and engineer tried to correct this by making the remaining storeys
shorter on the uphill side - but to no avail. It kept leaning more and more.
The lean, first noted when three of the tower's
eight storeys had been built, resulted from the foundation stones being laid on soft ground
consisting of clay, fine sand and shells.
The next storeys were built slightly taller on the short side of the tower in an
attempt to compensate for the lean. However, the weight of the extra floors caused the edifice to
sink further and lean more.
