When was leaning tower of pisa erected

Please enable JavaScript on your browser to best view this site. The construction of the Leaning Tower of Pisa began in August It 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. The Tower of Pisa is the churches belltower.

The city of Pisa was at the beginning a simple but important Italian seaport. With its growth, so did its religious buildings. Its fame and power grew gradually over the years, as the people of Pisa were involved in various military conflicts and trade agreements.

Construction then stopped again until when the last floor was built. In the same year, the bell was finally installed. The Leaning Tower of Pisa holds a significant place in world history as well. Famous physician Galileo Galilei once dropped two cannon balls of different masses from the Tower to demonstrate their speed of descent was independent of their mass. After some years, Italian dictator Benito Mussolini commanded the Tower to be righted.

So cement was poured into its foundation but the consequences were disappointing as it simply sank further into the soft soil. Reflecting more on the history of the Leaning Tower, it is interesting to note 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 , the Leaning Tower of Pisa was closed as there was a threat of collapse. It had been discovered that the Tower was subsiding at the rate of 0.

It seems the whole city of Pisa is built on the same kind of unstable soil. However, in there was no precedent case and the builders had to stop the works while looking for a solution. Meanwhile, Pisa got involved into a long was with the nearby city-state of Genova and the works for the Tower were halted for about years. It took years to complete this incredible piece of art and engineering.

In works resumed with the objective to compensate the lean and to build the Tower up to the 7th tier. It was a challenging operation since the Tower was now tilted on one side. At the time, no one ever attempted a similar operation. The engineer Giovanni de Simone took up this massive challenge.
