You cruise right into the heart of historic Cadiz as immediately across the busy Avenida del Puerto from the Spanish port is the main square and shopping area. From there, it is easy to find your own way around this compact city. Behind is the 18th century cathedral (El Nueva) and the view from the top is worth the long climb up its internal stairs. The narrow streets of the old town below are lined by tall Moorish-style houses with flower-decked balconies mixed in amongst some small shops and tapas bars. Cadiz dates back to the 12th century BC so is the oldest continuously inhabited city in the western world but sultry Seville has long since outgrown its neighbour. La Giralda (the bell-tower next to its Gothic cathedral), is in Sevilles historic Jewish quarter which also has the whitewashed houses and exquisitely coloured bougainvillea that everyone associates with this lovely city.
