Athens metropolitan area

The Athens metropolitan area spans 2,928.717 km (1,131 sq mi) within the Attica region and includes a total of 58 municipalities, which are organized in seven regional units (those outlined above, along with East Attica and West Attica), having reached a population of 3,638,281 according to the 2021 census. Athens and Piraeus municipalities serve as the two metropolitan centres of the Athens Metropolitan Area. There are also some inter-municipal centres serving specific areas. For example, Kifissia and Glyfada serve as inter-municipal centres for northern and southern suburbs respectively.

The Athens Metropolitan Area consists of 58 densely populated municipalities, sprawling around the Municipality of Athens (the City Centre) in virtually all directions. For the Athenians, all the urban municipalities surrounding the City Centre are called suburbs. According to their geographic location in relation to the City of Athens, the suburbs are divided into four zones; the northern suburbs (including Agios Stefanos, Dionysos, Ekali, Nea Erythraia, Kifissia, Kryoneri, Maroussi, Pefki, Lykovrysi, Metamorfosi, Nea Ionia, Nea Filadelfeia, Irakleio, Vrilissia, Melissia, Penteli, Chalandri, Agia Paraskevi, Gerakas, Pallini, Galatsi, Psychiko and Filothei); the southern suburbs (including Alimos, Nea Smyrni, Moschato, Tavros, Agios Ioannis Renti, Kallithea, Piraeus, Agios Dimitrios, Palaio Faliro, Elliniko, Glyfada, Lagonisi, Saronida, Argyroupoli, Ilioupoli, Varkiza, Voula, Vari and Vouliagmeni); the eastern suburbs (including Zografou, Dafni, Vyronas, Kaisariani, Cholargos and Papagou); and the western suburbs (including Peristeri, Ilion, Egaleo, Koridallos, Agia Varvara, Keratsini, Perama, Nikaia, Drapetsona, Chaidari, Petroupoli, Agioi Anargyroi, Ano Liosia, Aspropyrgos, Eleusina, Acharnes and Kamatero).

The Athens city coastline, extending from the major commercial port of Piraeus to the southernmost suburb of Varkiza for some 25 km (20 mi), is also connected to the City Centre by tram.

In the northern suburb of Maroussi, the upgraded main Olympic Complex (known by its Greek acronym OAKA) dominates the skyline. The area has been redeveloped according to a design by the Spanish architect Santiago Calatrava, with steel arches, landscaped gardens, fountains, futuristic glass, and a landmark new blue glass roof which was added to the main stadium. A second Olympic complex, next to the sea at the beach of Palaio Faliro, also features modern stadia, shops and an elevated esplanade. Work is underway to transform the grounds of the old Athens Airport – named Elliniko – in the southern suburbs, into one of the largest landscaped parks in Europe, to be named the Hellenikon Metropolitan Park.

Many of the southern suburbs (such as Alimos, Palaio Faliro, Elliniko, Glyfada, Voula, Vouliagmeni and Varkiza) known as the Athens Riviera, host a number of sandy beaches, most of which are operated by the Greek National Tourism Organisation and require an entrance fee. Casinos operate on both Mount Parnitha, some 25 km (16 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 Athens Suburban Railway).
