1. Winter in Venice

With unprecedented access to Venice's emergency and public services this series goes behind the 15th-century facades to experience the real, living city. From daily emergencies to street sweeping, bridge maintenance to flood defence systems and a death-defying descent across St Mark's Square, this is Venice as you have never seen it before. This is Venice 24/7.\n\nVenice is masked by sheets of snow. The emergency services negotiate choppy waters to deal with daily hazards as well as life-and-death emergencies. There is a sunken boat to save, an elderly lady with a suspected stroke and, in this city built on wood, the most dreaded call of all - fire. We see how Venice deals with thousands of tonnes of rubbish, turning it into power which is fed back into the city. Venice may be over 1,000 years old, but staying afloat requires 21st-century innovation.
