Athens, the capital and largest city in Greece, dominates the Attica periphery: as one of the world's oldest cities, its recorded history spans at least 3,000 years. The Greek capital has a population of 745,514 (in 2001) within its administrative limits and about 5 million in the Metro area.

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.

Classical Athens was a powerful city-state. A center for the arts, learning and philosophy, home of Plato's Academy and Aristotle's Lyceum, Athens was also the birthplace of Socrates, Pericles, Sophocles, and its many other prominent philosophers, writers and politicians of the ancient world. It is widely referred to as the cradle of Western civilization and the birthplace of democracy, largely due to the impact of its cultural and political achievements during the 5th and 4th centuries BC on the rest of the then known European continent.

Athens was the host city of the first modern-day Olympic Games in 1896, and 108 years later it welcomed home the 2004 Summer Olympics, with great success.

In the 1980s it became evident that smog from factories and an ever increasing fleet of automobiles, as well as a lack of adequate free space due to overcongestion, had evolved into the city's most important challenges. A series of anti-pollution measures taken by the city's authorities in the 1990s, combined with a substantial improvement of the city's infrastructure (including the Attiki Odos ring road, the dramatic expansion of the Athens Metro, and the brand new Athens International Airport), alleviated pollution considerably and transformed Athens into a much more functional city.

The Athens Metropolitan Area consists of 73 densely populated municipalities, sprawling around the city in virtually all directions. According to their geographic location in relation to the city of Athens, the suburbs are divided into four zones; the northern suburbs (including Ekali, Nea Erythrea, Agios Stefanos, Drosia, Kryoneri, Kifissia, Maroussi, Pefki, Lykovrisi, Heraklio, Glyka Nera, Vrilissia, Melissia, Pendeli, Halandri, Psychiko and Filothei); the southern suburbs, (including Palaio Faliro, Elliniko, Glyfada, Alimos, Voula and the southernmost suburb of Vouliagmeni); the eastern suburbs, (including Zografou, Vyronas, Kaisariani, Cholargos, Papagou and Aghia Paraskevi; and the western suburbs (including Peristeri, Ilion, Egaleo, Petroupoli and Nikaia). The northern and most of the southern suburbs are particularly affluent districts, inhabited primarily by middle-to-high and high income groups. The western suburbs are primarily resided in by middle income earners, with some areas resided in by middle-to-low income groups and still others by middle-to-high earners; while the eastern suburbs are primarily inhabited by middle and middle-to-high income groups.

The Athens city coastline, extending from the major commercial port of Piraeus to the southernmost suburb of Varkiza for some 50 km (30 mi), is also connected to the city centre by a tram (which, although modern, can be slow during rush hour), and is punctuated by a string of popular restaurants, cafes, vibrant music venues and modern sports facilities. The area is particularly packed with fashionable bars and nightclubs, that are literally crowded by the city's youth on a daily basis. Most of all during the summer months, the elegant coastal suburbs of Glyfada, Voula and Vouliagmeni host countless such meeting-points, continuing the length of Poseidonos Avenue and Alkyonidon Avenue.

The city is surrounded by four mountains; (Parnitha and Penteli accessible to the north, Hemmettus to the southeast, and Egaleo to the west). Mount Parnitha, in particular, is the tallest of the city (1,453 m (4,767 ft)) and has been declared a national park. Tens of well-marked paths, gorges, springs, torrents and caves dot the area, and one may even encounter deer in its dense forest. Hiking and mountain-biking in all four mountains have been and remain popular outdoor activities for many Athenians. Casinos operate on both Mount Parnitha, some 30 km (19 mi) from downtown Athens, (accessible by car or cable car) and the nearby town of Loutraki (accessible by car via the Athens - Corinth National Highway, or the suburban railroad).
