The Earth as we all know is created with many beautiful sceneries. In every corner of the world, there is something you could stare at and be in awe. Wonders of the world which may serve as an inspiration to a person. One is the Leaning Tower of Pisa, famous for its inclination. It is also said to be the testing ground for Galileo’s experiments on gravity.

The Tower of Pisa serves as the campanile or the freestanding bell tower of the Cathedral of the Italian city of Pisa. It is positioned behind the cathedral and is the third oldest structure in Pisa’s cathedral square after the Cathedral and the Baptistry. The tower is 183.27 ft from the low side and 186.02 ft from the high side. The width of the walls at the base is 4.09 m (13.42 ft) and at the top 2.48 m (8.14 ft). Its weight is estimated at 14,500 metric tons(16,000 short tons).
