There are many places in the world which are able to gather the attention of those who love to travel. Some of those places are unique and very attractive. Leaning tower of Pisa is one of those places which are considered to be very well known internationally. These places represent the countries in which these are located. The buildings like leaning tower of Pisa carry with them an aura of the era they belong to. This tower is a bell tower. It is a free standing one, but the most important thing about it is that it leans naturally. There is no logical reason behind its leaning, but the tower leans anyway. The Tower is located in the city of Pisa, in Italy. When the tower was built, it was supposed to be a straight and well erected one. Soon after its construction started in 1173, it started leaning towards the south east. The one reason you can point out for its leaning is the weak foundation and loose substrate due to the presence of which the tower now leans. It is standing in the leaning position for the past many centuries.
