"See the Leaning Tower.... well..." The Tower Tip by margaretvn

See the Leaning Tower.... well you can't miss it really!
The leaning tower of Pisa is a medieval structure which is famous for the settling of its foundation. This movement of the foundation causes it to lean 5.2 m from the perpendicular. Three of towers eight stories were completed when the uneven settling of the building's foundation in the soft ground became noticeable. Bonnano Pisano, the engineer in charge, tried to compensate for the lean by making the new stories slightly taller on the short side, but the extra masonry caused the structure to sink still further. Engineers looked for solutions and work was stopped several times, but the tower was finished,( still leaning) in the 14th century. The bell tower, which was begun in 1174 as the third and final structure of the city's cathedral complex, was designed to stand 56 m high and was made of white marble.
