Barcelona is the cultural heartland of Spain, yet its first language is Catalan, the native tongue of the proudly independent Catalonia region. Stroll down the shady, tree-lined Ramblas between street musicians and elegant bistros. Then perhaps visit the venerable Gothic cathedral, Picasso Museum or enjoy the architectural genius of Antonio Gaudi's Church of the Holy Family.

Lisbon is many cities, from the cobbled alleys of the Alfama district to the broad Parisian style avenues at its heart. View it all from the heights of St. George's Castle. Belem's Monument to the Discoveries recalls the seafaring past, while nearby Sintra's storybook palaces, and the seaside resort of Caiscais, have different tales to tell.

One of the "Pillars of Hercules," Gibraltar is an historic landmark with British and Spanish influences. Guarding the entrance to the Atlantic, the great rock still serves as Britain's threshold to the Mediterranean. Take a cable car to the top of the rock for a spectacular view of two continents as well as the famous Barbary apes.
Situated on Spain's Costa del Sol, Malaga is the region's capital and a popular holiday destination. At the same time, the city is known as the birthplace of Pablo Picasso and for the sweet Malaga dessert wines that come from the hilly vineyards just outside of town. Other points of interest include impressive Gothic architecture, remains of a Moorish castle, and several interesting museums.
A major seaport and naval base, it has a fine natural harbor, protected by forts. It was founded in 225 B.C. and soon became a flourishing port: the chief Carthaginian base in Spain. The medieval Castillo de la Concepcion, whose ruins are surrounded by fine gardens, commands a splendid view of the city and harbor. No traces of the ancient city remain.

The most populated city in France after Paris, Marseille has all the sights and sounds of a Mediterranean melting pot, which it has been ever since the Phocaean Greeks invaded around 600 B.C. Its industrial docks rub shoulders with the picturesque old harbor, the Vieux Port, founded by the Greeks 2,600 years ago. Packed with colorful fishing boats and yachts, the Vieux Port is the heart of Marseille.
Located on the Riviera di Ponente, southwest of Genoa, Savona dates back to third century BC and features excellent examples of medieval, Renaissance, and Baroque architecture. Visit the Renaissance cathedral, the Capella Sistina, and the Palazzo della Rovere, built by Pope Julius II.
