3. City Fit for a Pope

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've never seen it before. This is Venice 24/7.\n\nThe city is on lockdown, with the pope visiting for the first time in a quarter of a century. There's a fractious relationship between Venice and the Vatican and it's a risky occasion for all involved, so security is tight and the emergency teams are on high alert. There are the specially selected papal gondoliers carrying on the family tradition, vital underwater security sweeps and tension as police attempt to shut down Grand Canal.
