"Venice is built on a swamp, so of course it's sinking," my hotel manager Gilberto tells me.
But at the moment Venice is sinking under the weight of tourists. Twenty-two million of them every year. And every year a thousand residents leave permanently.
So, with the additional threat of rising sea-levels, can Venice survive? Should you rush to see this legendary city before it disappears? Or will massive engineering efforts see it withstand the elements and remain one of the planet's architectural wonders?
John Maddocks poses the question and examines efforts to save the UNESCO World Heritage city.
