Lisbon

Lisbon can once again lay claim to the name Golden City of southern Europe. As Portugal 's capital, the city struggled through a few decades before getting a breath of fresh air by way of a modern cosmopolitan facelift. The 1990s brought a lot of change and improvements to a city already rich with history and culture.

River Tagus is now spanned by the unbelievably breathtaking Vasco da Gama Bridge, making many other regions of Portugal easily accessible. An easy connection to the rest of Europe can also be found by way of the architectural wonder of Santiago Calatrava's Gare do Oriente, the transportation hub of Lisbon. A marvel to see under the glimmer of sunlight, it is a dazzling spectacle when illuminated at night. Cross the street and you are at the 1998 World Expo's Parque das Nações.

Delve into the fascinating past with a visit to Castelo Sao Jorge, an impressively fortified castle which looms over the city since medieval times. Though greatly destroyed in the earthquake of 1755, remnant's of Lisbon 's golden age can still be seen. You'll be charmed and delighted as you stroll past inviting cafes set amidst Romanesque, Barocque and Gothic architecture.

Ancient art can be viewed at the Museu Nacional de Arte Antiga, while the Museu Nacional do Traje e da Moda offers a fascinating glimpse into the world of costume and fashion. For a captivating night at the opera, check the calendar of Teatro Nacional de Sao Carlos. You'll also be impressed by Oceanario de Lisboa, the second largest oceanarium in the world.
