Description Vasari reports that the tower was begun by Bonanno Pisano, but modern research indicates the plan may have
been by Gherardo di Gherardo. The uneven settling of the campanile's foundations during its construction caused the tower to
lean. The work was continued by Giovanni Pisano and Giovanni di Simone in 1275, with the addition of another three floors in
a direction that bent opposite to the inclination to compensate for the flaw; but the added weight caused the tower to lean
even more. According to Vasari, Tommaso di Andrea Pisano completed the belfry between 1350 and 1372. Modern efforts are
underway to prevent the further leaning and ultimate collapse of the tower.
