Why is the leaning tower of Pisa tilted, which is the seventh wonder of the world, completed in almost 200 years?
This tower was designed by Guglielmo and Bonanno Pisano. Recent studies have shown that Diotisalvi was also involved. The construction of this tower started 800 years ago in the year 1172 and was completed only in 1373. It took 199 years to build this tower. The architect who built this tower dug a foundation only three meters deep because the soil under the ground is strong. However, when three floors were built, the soil of the foundation became muddy and the tower started to fall to one side. Then the construction of this tower was stopped.
At that time, the Republic of Pisa was at war with other republics, so the construction of the tower was stopped for more than 100 years. It was good because the foundation of the tower was strengthened and reached the moat. And, the construction of the tower went ahead again and was completed.
Although the building had three floors, the architect built it so that it was low on one side and high on the other side because it was sloping on one side. Many attempts were made to make it simple, but it was not possible. Now this tower is falling to one side at the rate of 1 mm every year. It is considered one of the most amazing towers in the world due to the fact that it is tilted to one side like a silver circle in a black cloud. If it continues to fall like this, this tower may collapse one day, but modern technology can save it.
