Fly with Austrian Airlines to Athenand experience the home of Aristotle's Academy and Plato's Lyceum. Take in the splendors of the origins of democracy and Western civilization that set the pattern for the development of Europe and the New World. Athens has been continuously inhabited for more than 7000 years, and evidence of the lifestyle of all the past generations is plentiful in the modern city. Modern development has taken a heavy toll on the environment of Athens although anti pollution measures, together with infrastructure modernization schemes that have been undertaken in the past two decades, have shown a considerable improvement. Athens may be densely populated but the National Garden of Athens, with its 15.5 hectares of grounds, is a welcome oasis in the center of the city.
