Twenty years ago, Professor Burland, from Imperial’s Department of Civil and Environmental Engineering, took part in a major international effort to rescue the 800-year old tower, which was in danger of complete collapse.
The tower just continued to lean, and because of the difficulties the construction was stopped. In 1234, the architect Benenato discovered that the tower was leaning even more. Now the south side of the fourth story was a full 6 inches shorter than the north side. He added a fifth story, again making the south columns taller than the north ones.
In 1350 Tommaso Pisano started work on the eighth story of the tower, the bell chamber. He found that the tower was still sinking, and so he made the spiral stairs inside the tower and the wall of the bell chamber higher on the south side than on the north.
The tower is situated behind the Pisa Cathedral and is the third-oldest structure in the city’s Cathedral Square ( Piazza del Duomo ), after the cathedral and the Pisa Baptistry . The height of the tower is 55.86 metres (183 feet 3 inches) from the ground on the low side and 56.67 m (185 ft 11 in) on the high side.
