4. The Biennale

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 art world descends on Venice for the Biennale, a six-month long festival. Anish Kapoor attempts to stage his ethereal Ascension in a challenging Palladian church while another artist battles to transport a four-tonne sculpture along the canal. The Fenice theatre undergoes critical safety checks, following the devastating fire of 1996 and a 100,000-tonne cruise-liner must execute inch-perfect manoeuvres as it travels perilously close to the historic centre.
