History
The free-standing bell tower of Pisa Cathedral was built in several phases with white marble arcades. It began to lean during construction because the ground subsided unevenly. Long pauses and adjustments to the upper storeys allowed work to continue despite the settlement. Modern stabilisation reduced the tilt, and the building reopened to visitors in 2001.
