A Leaning Tower of Venice
Here in Venice there is not one but several torri pendenti, although, admittedly, none lean quite so dramatically as the one in Tuscany.
The campanile of Santo Stefano is a good example.
While the tower was being shored up, between 1902 and 1903, the bells were rendered out of action and so the church was provided with a tiny belfry as a substitute.
As soon as work on the campanile had been completed, the belfry became redundant.
The two bells were removed, but the belfry remains.
