Athens has been a destination for travellers since antiquity. Over the past decade, the city's infrastructure and social amenities have improved, in part because of its successful bid to stage the 2004 Olympic Games. The Greek Government, aided by the EU, has funded major infrastructure projects such as the state-of-the-art Eleftherios Venizelos International Airport, the expansion of the Athens Metro system, and the new Attiki Odos Motorway.
