Barcelona, Lisbon, Leixoes, Southampton

Barcelona is one of the world's greatest treasures, a global capital of commerce, fashion, culture and sunshine. Cruise visitors should start with a walk down Las Ramblas, the glorious tree-shaded thoroughfare at the heart of the city, enjoy a dive in the wonderful beaches nearby, but, most of all, see what visionary architect Antoni Gaudi wrought. Seven of his creations have been honored as UNESCO World Heritage Sites, including La Sagrada Familia, the Park Guell and Casa Mila. Time provided, you can also visit the former Olympic Ring on the hill of Montjuic, home to world-class parks, fountains and museums. Barcelona, which nurtured such artistic giants as Picasso, Dali, Miro and Casals, is definitely a traveler's paradise.

Lisbon, the capital of Portugal, on the southwest of the country, has been the main gateway for the rest of the planet for more than 19 centuries. Ships captained by Portuguese explorers like Bartolomeu Dias, Vasco da Gama and Ferdinand Magellan, skittered across the globe, hauling treasure home and making Lisbon a global capital. Draped across seven hills, Lisbon was once the center of a vast maritime empire that stretched from the west coast of Africa to the Spice Islands of the East Indies, until 1755, when a violent earthquake destroyed two-thirds of the city, leaving intact only the Alfama, the old Moorish quarter. Today, Lisbon is a stately city of Neoclassical buildings and wide plazas. Eternally linked to the sea, Lisbon's magnificent harbor is spanned by the longest suspension bridge in Europe. Among the city's landmarks are the iconic Castelo de São Jorge, the World Heritage Sites of Belém Tower and Jerónimos Monastery, both built in Lisbon's native Manueline architectural style.
