What is the angle of the Leaning Tower of Pisa?
Leaning Tower of Pisa
In 1272, construction resumed under Giovanni di Simone, architect of the Camposanto. In an effort to compensate for the tilt, the engineers built upper floors with one side taller than the other. Because of this, the tower is curved.[9] Construction was halted again in 1284 when the Pisans were defeated by the Genoans in the Battle of Meloria.
