AMAZING STRUCTURE

Hi everyone! Today i will tell you about Pisa tower.The tower of Pisa is one of the most popular buildings in Europe.It's impressive ancient tower, which has an interesting history and features.This building is in Italy. The history of Pisa is a little bit unusually, because tower that tower supposed to lean. Many tourists visited this tower 

From the sources that i've got, the origin of this tower is the tower was begun to construct in 1173 and after the first three stories were built, the ground started to sink, because of water under the ground. Four more floors were constructed in to make-up for the inclination. The construction stopped again until 1372 when the last floor of the Leaning Tower of Pisa was built. In other words, Tower of Pisa may be leaning because of a blunder mistake by engineers. 

The leaning tower of Pisa is 18 degrees to the west.The top of the leaning tower of Pisa is about 17 feet off the vertical. 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 is also slightly curved from the attempts by various architects to keep it from leaning more or falling over.

So what do you think about this tower? Amazing? Fascinating? Yep, at least, Pisa tower such a great tower that i've ever observed.I wish someday i had a chance to go there.
