Euboea in the context of "Greek peninsula"

The Aegean Sea is an elongated embayment of the Mediterranean Sea between Europe and Asia. It is located between the Balkans and Anatolia, and covers an area of some 215,000 km (83,000 sq mi). In the north, the Aegean is connected to the Marmara Sea, which in turn connects to the Black Sea, by the straits of the Dardanelles and the Bosphorus, respectively. The Aegean Islands are located within the sea and some bound it on its southern periphery, including Crete and Rhodes. The sea reaches a maximum depth of 2,639 m (8,658 ft) to the west of Karpathos. The Thracian Sea and the Sea of Crete are main subdivisions of the Aegean Sea.

The Aegean Islands can be divided into several island groups, including the Dodecanese, the Cyclades, the Sporades, the Saronic islands and the North Aegean Islands, as well as Crete and its surrounding islands. The Dodecanese, located to the southeast, includes the islands of Rhodes, Kos, and Patmos; the islands of Delos and Naxos are within the Cyclades to the south of the sea. Lesbos is part of the North Aegean Islands. Euboea, the second-largest island in Greece, is located in the Aegean, despite being administered as part of Central Greece. Nine out of twelve of the Administrative regions of Greece border the sea, along with the Turkish provinces of Edirne, Çanakkale, Balıkesir, İzmir, Aydın and Muğla to the east of the sea. Various Turkish islands in the sea are Imbros, Tenedos, Cunda Island, and the Foça Islands.

Greece is a country in Southeastern Europe, on the Balkan Peninsula. It is bordered to the north by Albania, North Macedonia and Bulgaria; to the east by Turkey, and is surrounded to the east by the Aegean Sea, to the south by the Cretan and the Libyan seas, and to the west by the Ionian Sea which separates Greece from Italy.

The country consists of an extremely rough, mountainous, peninsular mainland jutting out into the Mediterranean Sea at the southernmost tip of the Balkans, and two smaller peninsulas projecting from it:the Chalkidiki and the Peloponnese, which is joined to the mainland by the Isthmus of Corinth. Greece also has many islands, of various sizes, the largest being Crete, Euboea, Lesvos, Rhodes, Chios, Kefalonia, and Corfu; groups of smaller islands include the Dodecanese and the Cyclades. According to the CIA World Factbook, Greece has 13,676 kilometres (8,498 mi) of coastline, the largest in the Mediterranean Basin.

Greece has many islands, with estimates ranging from somewhere around 1,200 to 6,000, depending on the minimum size to take into account. The number of inhabited islands is variously cited as between 166 and 227.

The largest Greek island by both area and population is Crete, located at the southern edge of the Aegean Sea. The second largest island in area is Euboea or Evvia, which is separated from the mainland by the 60 m wide Euripus Strait, and is administered as part of the Central Greece region. After the third and fourth largest Greek islands, Lesbos and Rhodes, the rest of the islands are two-thirds of the area of Rhodes, or smaller.

Continental Greece (Greek: Στερεά Ελλάδα, romanized: Stereá Elláda; formerly Χέρσος Ἑλλάς, Chérsos Ellás), colloquially known as Roumeli (Ρούμελη), is a traditional geographic region of Greece. In English, the area is usually called Central Greece, but the equivalent Greek term (Κεντρική Ελλάδα, Kentrikí Elláda) is more rarely used.

It includes the southern part of the Greek mainland (sans the Peloponnese), as well as the offshore island of Euboea. Since 1987, its territory has been divided among the administrative regions of Central Greece and Attica, and the regional unit (former prefecture) of Aetolia-Acarnania in the administrative region of Western Greece.

The (Northern) Sporades are an archipelago along the east coast of Greece, northeast of the island of Euboea, in the Aegean Sea. They consist of 24 islands, four of which are permanently inhabited: Alonnisos, Skiathos, Skopelos and Skyros. They may also be referred to as the Thessalian Sporades (Θεσσαλικές Σποράδες).

Central Greece (Greek: Περιφέρεια Στερεάς Ελλάδας, romanized: Periféreia Stereás Elládas, Greek pronunciation: [periˈferia stereˈas eˈlaðas], colloquially known as Ρούμελη (Roúmeli)) is one of the thirteen administrative regions of Greece. The region occupies the eastern part of the traditional region of Central Greece, including the island of Euboea. To the south it borders the regions of Attica and the Peloponnese, to the west the region of Western Greece, to the north the region of Thessaly and to the northwest it shares a small border with Epirus. Its capital city is Lamia and the largest city is Chalcis.

Kefalonia or Cephalonia (Greek: Κεφαλονιά), formerly also known as Kefallinia or Kephallenia (Κεφαλληνία), is the largest of the Ionian Islands in western Greece and the 6th-largest island in Greece after Crete, Euboea, Lesbos, Rhodes and Chios. It is also a separate regional unit of the Ionian Islands region. It was a former Latin Catholic diocese Kefalonia–Zakynthos (Cefalonia–Zante) and short-lived titular see as just Kefalonia. The largest cities of Cephalonia are Argostoli and Lixouri.
