Famous architects and engineers from all over the Roman Empire were called to Florence to try their hand at straightening the Tower. By the time they completed the seventh floor and bell chamber, the angle of the tilt was 1.6Г‚В°. It does sound laughable now, but over a millennium ago, this seemed like the best option to straighten the Tower. In 1272, architect Giovanni di Simone compensated for the minor tilt by making the next few stories higher on the south side, which led to it sinking even further. So, what did they do then? Answer Гўв‚¬вЂњ they gave up.Д¬onstruction was halted for over a century due to wars in Italy, giving the soil time to settle. The pressure from the top levels would sink the structure and increase the lean if workers added more weight. Less than 5 years later, the south side of the tower was already underground. The TowerГўв‚¬в„ўs first architects thought that a three-foot deep foundation would be sufficient for an 8-storey monument, oblivious to the fact that the ground underneath the coastal city was marshy, made of clay mud and wet sand. The monument, known today as the Leaning Tower of Pisa, gave architects the worst of headaches until the 20th century. Construction of a free-standing campanile, or bell tower, began in 1173. The existing church was renovated and enlarged, and a great domed baptistery was built on the plaza. Did you know that the name of the town of Pisa comes from a Greek word meaning Гўв‚¬Лњmarshy landГўв‚¬в„ў? Yeah, neither did the architects who were involved with constructing a spectacular monument in the 12th century.
