How the leaning tower become leaning

The leaning tower of Pisa, in italy is famous because of its tilt. An inscription on the right hand corner above the entrance said that construction began in 1173. It was built as bell tower to wake up people to go to church or warn them of emergencies. It was or so built to show the  wealth and power of Pisa.

When they got to the 3rd storey the building started to sink because the subsoil was weak and the foundation was not strong or sturdy. As you go up the spiral staircase there are 300 well worn stone steps when you reach to the top you can see a panoramic view of Pisa.

At the top of the tower it should be vertical but it’s not. Now today it is almost 4m where it should be. The tilt was worsening because of the weak subsoil underneath the poorly laid foundation. So they compensated for the tilt by constructing 1 side of the tower taller than the other.
