The Lean
Only 5 years after work on the building began, it was leaning noticeably to the North. The lean was first noticed during construction of the third floor. During the building of the next three floors, the lean was corrected by building the floors parallel to the ground, and not level with the leaning building. During this phase the tower started to lean the other way. Now it was leaning to the South.
Why the lean?
The tower is built on unsuitable ground for such a heavy and tall building. It is only about 6 feet above sea level and built on a riverbed. The underlying ground is made up of layers of sand and clay. The layers are not even and the weight of the building has compressed them. Because the layers are not even, as the ground has compressed, it has sunk more in some places than others.

Pisa used to be the port for Florence and the basic trade for all of Tuscany. Pisa's port, however, silted up and that silt is what they built the tower on. the tower is not bent, it is leaning and the government is doing all it can to keep it from falling over. However they don't want to take the lean out because of the fear of stopping tourist trades in Pisa.
The port for the Arno River is now Livorno, a beautiful city located on the Mediterranean
There is a nice big word for the type of soil on which the tower is built, probably two words - micacous which would mean to me that the mica in the soil is so abundant that the particles of earth cannot be held together like the ground in your front yard, it will give. The other is alluvium.

When the bell tower was first built, it was about halfway finished when it began to lean. The builders realized it was sitting partly on a softer area of ground. Rather than take a chance on the whole thing falling down, they corrected for it by building the rest of the tower at an angle to try to offset the lean. That's one reason engineers are suggesting they build up the earth there with concrete--by stabilizing the soil, it would keep the tower from leaning more than it already does. But because the top part was built at an angle from the bottom, it will never be completely straight.

theres a river below the Pisa Tower

the ground has subsided underneath it so the footings have sunk on one side. This problem was known when it was being built and there is a correction in the building angle about a quarter of the way up

The foundation is not adequate. A tall building that does not rest on bedrock, and elaborate engineering has been required to stabilized it.

its not bended, its leaning over. They built it on unstable soil and a sink hole has been developing under one side of it causing it to lean. They built counter weights on one side of it and anchored it with huge cables so its still leaning today.

it was built on soft foundation and sinking but contractors are correcting this by shoring up the foundation with concrete
