Leaning Tower of Pisa
The Leaning Tower of Pisa was meant to be the Bell Tower of Pisa, Italy. Construction began on the beautiful tower in 1173, and the architect is still unknown to mankind. The tower was designed to be a vertical building. The 14, 500t (16, 000 tn) building began to tilt during construction. Earlier builders of the time tried to add weights to the side opposite of the lean to get the building to lean the opposite direction, but this actually worsened the lean. The lean originally came because the tower was built on clay and began to lean during a break in construction because the clay sediments had time to compact. Many builders attempted to fix the lean by adding more soil to the leaning side to straighten the structure, which now leans four meters off center. This has helped the tower greatly by leveling the ground beneath the great building, hopefully allowing us to enjoy the beautiful tower for many more years to come!
