Timothy West and Prunella Scales embark on more spectacular canal journeys. This time they travel to Venice. The journey begins 14 miles west of Venice on the Brenta, a river that was first canalised in the 13th century. Lined with palaces that were once holiday homes for Venetian nobility, they follow the route that Casanova and Lord Byron took to the city. After crossing the Venetian lagoon, Tim and Pru arrive at St Mark's Square, where they escape the busy Grand Canal and discover the tranquillity and beauty of the smaller canals that tourists rarely see. Their journey's end is on the marshy island of Torcello, the place where Venice began.
