Cadiz (Seville), Spain
To taste the true flavor of this ancient port city, one should stroll its seaside promenade, pausing to rest beneath the huge banyan trees. The narrow, winding streets of the old town fan out from the port, leading you to sunny, palm-lined plazas. Visit the Catedral Nueva (New Cathedral), begun in the early 1800s but not completed for 116 years. Its dramatic, golden dome rises over a striking interior. For those who enjoy people-watching as much as sightseeing, the seafood restaurants along the eastern edge of the port provide the ideal setting.
