Greece is strategically located at the crossroads of Europe, Asia and Africa. It also shares land borders with Albania to the northwest, the Republic of Macedonia and Bulgaria to the north and Turkey to the northeast. The country consists of nine geographic regions: Macedonia, Central Greece, the Peloponnese, Thessaly, Epirus, the Aegean Islands (including the Dodecanese and Cyclades), Thrace, Crete, and the Ionian Islands. The Aegean Sea lies to the east of the mainland, the Ionian Sea to the west, and the Mediterranean Sea to the south. Greece has the longest coastline on the Mediterranean Basin and the 11th longest coastline in the world at 13,676 km (8,498 mi) in length, featuring a vast number of islands (approximately 1,400, of which 227 are inhabited). Eighty percent of Greece consists of mountains, of which Mount Olympus is the highest, at 2,917 m (9,570 ft).
Located in Southern Europe. Greece consists of a mountainous, peninsular mainland jutting out into the sea at the southern end of the Balkans, ending at the Peloponnese peninsula (separated from the mainland by the canal of the Isthmus of Corinth) and strategically located at the crossroads of Europe, Asia, and Africa,. Due to its highly indented coastline and numerous islands, Greece has the 11th longest coastline in the world with 13,676 km (8,498 mi); its land boundary is 1,160 km (721 mi). The country lies approximately between latitudes 34° and 42° N, and longitudes 19° and 30° E.
Greece features a vast number of islands, between 1,200 and 6,000, depending on the definition, 227 of which are inhabited. Crete is the largest and most populous island; Euboea, separated from the mainland by the 60m-wide Euripus Strait, is the second largest, followed by Lesbos and Rhodes.
Since the 1980s, the road and rail network of Greece has been significantly modernized. Important works include the A2 (Egnatia Odos) motorway, that connects northwestern Greece (Igoumenitsa) with northern and northeastern Greece (Kipoi); and the Rio–Antirrio bridge, the longest suspension cable bridge in Europe (2,250 m (7,382 ft) long), connecting the Peloponnese from Rio (7 km (4 mi) from Patras) with Antirrio in Central Greece.
