Pisa does not have one leaning tower but three, and the most tilted is not the famous one
The cathedral bell tower of Pisa, begun on 9 August 1173 and 57 metres high, now leans 3.97 degrees; in 1993, before the stabilisation works, its top was about 4.47 metres off the vertical, close to 5.5 degrees. But the soft clay and sand under the city has bent two other bell towers as well. The octagonal one of San Nicola, perhaps from the second half of the 13th century, with a spiral staircase running open around its inside, leans 2.5 degrees. The one of San Michele degli Scalzi, on the side facing the Arno, tips towards the river by 5 degrees: more than the Tower. Only nobody poses for a photo with it.
