Lisbon
Lisbon is one of the oldest cities in the world, and one of the oldest in Western Europe, predating other modern European capitals such as London, Paris, and Rome by centuries. Julius Caesar made it a municipium called "Felicitas Julia", adding to the name "Olissipo". Ruled by a series of Germanic tribes from the 5th century, it was captured by the Moors in the 8th century. In 1147, the Crusaders under Afonso Henriques reconquered the city and since then it has been a major political, economic and cultural centre of Portugal. Unlike most capital cities, Lisbon's status as the capital of Portugal has never been granted or confirmed officially – by statute or in written form. Its position as the capital has formed through constitutional convention, making its position as "de facto" capital a part of the Constitution of Portugal.
Lisbon
Humberto Delgado Airport is located within the city limits. It is the headquarters and hub for TAP Portugal as well as a hub for Easyjet, Azores Airlines, Ryanair, EuroAtlantic Airways, White Airways, and Hi Fly. A second airport has been proposed, but the project has been put on hold because of the Portuguese and European economic crisis, and also because of the long discussion on whether a new airport is needed. However, the last proposal is military air base in Montijo that would be replaced by a civil airport. So, Lisbon would have two airports, the current airport in north and a new in the south of the city.
