Venice is not just a stage set. It is also a city with a resident population, which has productive activities, transportation and services. But how does the â€śVenice systemâ€ť work? How do the tides in the lagoon behave? How are the canals formed? And the embankments? Whatâ€™s under the buildings? Venice Backstage, a project conceived by Insula spa, the operative arm of the City for urban maintenance, is about what happens behind the curtains, to make the fragile beauty of this fantastic city easier to appreciate.
