A bustling and cosmopolitan metropolis, Athens is central to economic, financial, industrial, political and cultural life in Greece. It is rapidly becoming a leading business centre in the European Union. Athens has been a popular destination for travelers since antiquity. Over the past decade, the city's infrastructure and social amenities have improved, in part due to 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.Athens is home to 148 theatrical stages, more than any other European city, including the famous ancient Herodes Atticus Theatre, home to the Athens Festival, which runs from May to October each year. In addition to a large number of multiplexes, Athens plays host to a variety of romantic, open air garden cinemas. The city also supports a vast number of music venues, including the Athens Concert Hall, known as the "Megaron Moussikis", which attracts world-famous artists all year round
