Follow the sun throughout September on a route brimming with historical and artistic interest. Dip into the pastel-colored streets of Lisbon, sample flamenco in andalucia and savour lazy days gazing over Italian marinas. Central to this cruise is a cultural week that visits Renaissance palaces, time travels to Pompeii and seeks out Greek legacies outside Catania. Around the Adriatic, bobbing gondolas and ports along Croatia's island shores nod to the ambitions of passing Venetian merchants.
