In 1174, engineer Bonnano Pisano laid a marble foundation large enough to park about 16 Ferrari 328s in and started building the campanile for the cathedral and baptistry of Pisa.
The Romanesque Tower of Pisa, comprising 14,000 tonnes of white marble, was completed 176 years later – but it was also embarrassingly crooked.
Because there was a lot of water under the ground in this area, Bonnano was able to place the foundation only about 10 feet down into the ground.
As the first story of the tower was completed, the south side began to sink.
The builders tried to make it look better by building the columns and arches on the south side about an inch taller than those on the north side.
However by the time they got to the fourth story, they had to make the southern columns 2 inches taller than the northern ones. The tower just continued to lean, and because of the difficulties the construction was stopped.
