Ten years ago, it still existed: house number zero. Unfortunately,
that's no longer the case. It was the address of the Corte dei conti in the Palazzo dei Camerlenghi.
As for whether the number - which was replaced by number 1 - was abandoned because of the ironic implication that the building was full of "zeros," that's certainly just a far-fetched theory. :)
