Why is the Leaning Tower of Pisa so important?
The Leaning Tower of Pisa, Italy, is famous simply because it leans! It is actually the bell tower of the cathedral of the city. Although it was designed to stand straight, the tower began leaning soon after the start of construction in 1173.

In an effort to compensate for the tilt, the engineers built the higher floors with one side taller than the other. This made the tower begin to lean in the other direction. Because of this the tower is actually curved.
It was interrupted several times by wars, debt and while engineers worked on solutions to correct the lean.
It is now realised 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 mid-1300s.
The tower stands 56 metres high, and until 1990 – was leaning over. It was estimated that the lean was increasing by one inch every 20 years.
