Арнольфо ди Камбио
The tower and its gate were elaborated in the designs of Arnolfo di Cambio for circumferential walls around Florence. These walls were, in the main, destroyed in the 19th century as a project of urban renewal, Risanamento, in part led by Giuseppe Poggi. This tower was spared, in part because of its panoramic view of the city. There are 160 steps to the summit.
