Greece Greece is located at the crossroads of Europe, Asia, and Africa. Situated on the southern tip of the Balkan Peninsula, it shares land borders with Albania to the northwest, the Republic of Macedonia and Bulgaria to the north, and Turkey to the northeast. The Aegean Sea lies to the east of the mainland, the Ionian Sea to the west, the Cretan Sea 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 large number of islands, of which 227 are inhabited. Eighty percent of Greece is mountainous, with Mount Olympus being the highest peak at 2,918 metres (9,573 ft). 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.
Turkey Turkey (Turkish: Türkiye [ˈtyɾcije]), officially the Republic of Turkey (Turkish: Türkiye Cumhuriyeti [ˈtyɾcije d͡ʒumˈhuɾijeti] ( listen)), is a transcontinental country in Eurasia, mainly in Anatolia in Western Asia, with a smaller portion on the Balkan peninsula in Southeast Europe.[7] Turkey is bordered by eight countries with Greece and Bulgaria to the northwest; Georgia to the northeast; Armenia, the Azerbaijan and Iran to the east; and Iraq and Syria to the south. The country is encircled by seas on three sides with the Aegean Sea to the west, the Black Sea to the north, and the Mediterranean Sea to the south. The Bosphorus, the Sea of Marmara, and the Dardanelles, which together form the Turkish Straits, divide Thrace and Anatolia and separate Europe and Asia.[8] Ankara is the capital while Istanbul is the country's largest city and main cultural and commercial centre, classified as a leading global city.[9]
