There are 10,134 inhabitants (2011 census), most of whom live in the largest town, Mykonos, which lies on the west coast. The town is also known as Chora (i.e. the Town in Greek, following the common practice in Greece when the name of the island itself is the same as the name of the principal town).

Kuşadası is a resort town on Turkey's Aegean coast, and the center of the seaside district of the same name within Aydın Province. Kuşadası is 95 km (59 mi) south of İzmir, and 71 km (44 mi) from Aydın. The municipality's primary industry is tourism.

Rhodes is the largest of the Dodecanese islands of Greece and is also the island group's historical capital. Administratively the island forms a separate municipality within the Rhodes regional unit, which is part of the South Aegean administrative region. The principal town of the island and seat of the municipality is Rhodes. The city of Rhodes had 50,636 inhabitants in 2011. It is located northeast of Crete, southeast of Athens and just off the Anatolian coast of Turkey. Rhodes' nickname is The island of the Knights, named after the Knights of Saint John of Jerusalem, who once conquered the land.

Historically, Rhodes was famous worldwide for the Colossus of Rhodes, one of the Seven Wonders of the Ancient World. The Medieval Old Town of the City of Rhodes has been declared a World Heritage Site. Today, it is one of the most popular tourist destinations in Europe. The name of the U.S. state of Rhode Island is thought to be based on this island.

Agios Nikolaos or Aghios Nikolaos is a coastal town on the Greek island of Crete, lying east of the island's capital Heraklion, north of the town of Ierapetra and west of the town of Sitia.

In the year 2011, the Municipality of Agios Nikolaos, which takes in part of the surrounding villages, claimed 27,074 inhabitants. The town is a municipality of the Crete region and sits partially upon the ruins of the ancient city of Lato pros Kamara.

Agios Nikolaos was settled in the late Bronze Age by Dorian occupants of Lato, at a time when the security of the Lato hillfort became a lesser concern and easy access to the harbour at Agios Nikolaos became more important.

The name Agios Nikolaos means Saint Nicholas. Its stress lies on the second syllable of the word "Nikolaos". Agios Nikolaos or Ayios Nikolaos (alternative romanizations of the Greek Άγιος Νικόλαος) is a common placename in Greece and Cyprus, since Saint Nicholas is the patron saint of sailors and of all of Greece.

Santorini, classically Thera, and officially Thira, is an island in the southern Aegean Sea, about 200 km (120 mi) southeast of Greece's mainland. It is the largest island of a small, circular archipelago, which bears the same name and is the remnant of a volcanic caldera. It forms the southernmost member of the Cyclades group of islands, with an area of approximately 73 km2 (28 sq mi) and a 2011 census population of 15,550. The municipality of Santorini includes the inhabited islands of Santorini and Therasia and the uninhabited islands of Nea Kameni, Palaia Kameni, Aspronisi, and Christiana. The total land area is 90.623 km2 (34.990 sq mi).Santorini is part of the Thira regional unit.

The island was the site of one of the largest volcanic eruptions in recorded history: the Minoan eruption(sometimes called the Thera eruption), which occurred about 3,600 years ago at the height of the Minoan civilization. The eruption left a large caldera surrounded by volcanic ash deposits hundreds of metres deep. It may have led indirectly to the collapse of the Minoan civilization on the island of Crete, 110 km (68 mi) to the south, through a gigantic tsunami. Another popular theory holds that the Thera eruption is the source of the legend of Atlantis.

It is the most active volcanic centre in the South Aegean Volcanic Arc, though what remains today is chiefly a water-filled caldera. The volcanic arc is approximately 500 km (310 mi) long and 20 to 40 km (12 to 25 mi) wide. The region first became volcanically active around 3–4 million years ago[citation needed], though volcanism on Thera began around 2 million years ago with the extrusion of dacitic lavas from vents around the Akrotiri.

Corfu or Kerkyra is a Greek island in the Ionian Sea. It is the second largest of the Ionian Islands, and, including its small satellite islands, forms the northwesternmost part of Greece. The island is part of the Corfu regional unit, and is administered as a single municipality, which also includes the smaller islands of Ereikoussa, Mathraki and Othonoi. The municipality has an area of 610,9 km2, the island proper 592,8 km2. The principal city of the island and seat of the municipality (pop. 32,095) is also named Corfu. Corfu is home to the Ionian University.

The island is bound up with the history of Greece from the beginnings of Greek mythology. Its history is full of battles and conquests. Ancient Korkyra took part in the Battle of Sybota which was a catalyst for the Peloponnesian War, and, according to Thucydides, the largest naval battle between Greek city states until that time. Thucydides also reports that Korkyra was one of the three great naval powers of fifth century BC Greece, along with Athens and Corinth. Medieval castles punctuating strategic locations across the island are a legacy of struggles in the Middle Ages against invasions by pirates and the Ottomans. Two of these castles enclose its capital, which is the only city in Greece to be surrounded in such a way. As a result, Corfu's capital has been officially declared a Kastropolis ("castle city") by the Greek government. From medieval times and into the 17th century, the island, having successfully repulsed the Ottomans during several sieges, was recognised as a bulwark of the European States against the Ottoman Empireand became one of the most fortified places in Europe. The fortifications of the island were used by the Venetians to defend against Ottoman intrusion into the Adriatic. Corfu eventually fell under British rule following the Napoleonic Wars. Corfu was eventually ceded by the British Empire along with the remaining islands of the United States of the Ionian Islands, and unification with modern Greece was concluded in 1864 under the Treaty of London.

In 2007, the city's old quarter was added to the UNESCO World Heritage List, following a recommendation by ICOMOS.

Corfu is a very popular tourist destination. The island was the location of the 1994 European Union summit.

In 1991, after the break-up of Yugoslavia, Dubrovnik was besieged by Serbian and Montenegrin soldiers of the Yugoslav People's Army (JNA) for seven months and suffered significant damage from shelling. After repair and restoration works in the 1990s and early 2000s, Dubrovnik re-emerged as one of the top tourist destinations in the Mediterranean.

The old Mediterranean port of Kotor is surrounded by fortifications built during the Venetian period. It is located on the Bay of Kotor (Boka Kotorska), one of the most indented parts of the Adriatic Sea. Some have called it the southern-most fjord in Europe, but it is a ria, a submerged river canyon. Together with the nearly overhanging limestone cliffs of Orjen and Lovćen, Kotor and its surrounding area form an impressive landscape.

Since the early 2000s Kotor has seen an increase in tourists , many of them coming by cruise ship. Visitors are attracted by the natural environment of the Gulf of Kotor and by the old town of Kotor.

Rome is the capital city and a special comune of Italy (named Comune di Roma Capitale). Rome also serves as the capital of the Lazio region. With 2,872,800 residents in 1,285 km2(496.1 sq mi), it is also the country's most populated comune. It is the fourth-most populous city in the European Union by population within city limits. It is the centre of the Metropolitan City of Rome, which has a population of 4,355,725 residents, thus making it the most populous metropolitan city in Italy. Rome is located in the central-western portion of the Italian Peninsula, within Lazio (Latium), along the shores of the Tiber. The Vatican City (the smallest country in the world) is an independent country inside the city boundaries of Rome, the only existing example of a country within a city: for this reason Rome has been often defined as capital of two states.

Rome's history spans 28 centuries. While Roman mythology dates the founding of Rome at around 753 BC, the site has been inhabited for much longer, making it one of the oldest continuously occupied sites in Europe. The city's early population originated from a mix of Latins, Etruscans, and Sabines. Eventually, the city successively became the capital of the Roman Kingdom, the Roman Republic and the Roman Empire, and is regarded as the birthplace of Western civilization and by some as the first ever metropolis. It was first called The Eternal City (Latin: Urbs Aeterna; Italian: La Città Eterna) by the Roman poet Tibullus in the 1st century BC, and the expression was also taken up by Ovid, Virgil, and Livy. Rome is also called the "Caput Mundi" (Capital of the World). After the fall of the Western Empire, which marked the beginning of the Middle Ages, Rome slowly fell under the political control of the Papacy, which had settled in the city since the 1st century AD, until in the 8th century it became the capital of the Papal States, which lasted until 1870. Beginning with the Renaissance, almost all the popes since Nicholas V (1447–1455) pursued over four hundred years a coherent architectural and urban programme aimed at making the city the artistic and cultural centre of the world. In this way, Rome became first one of the major centres of the Italian Renaissance, and then the birthplace of both the Baroque style and Neoclassicism. Famous artists, painters, sculptors and architects made Rome the centre of their activity, creating masterpieces throughout the city. In 1871, Rome became the capital of the Kingdom of Italy, which, in 1946, became the Italian Republic.

Rome has the status of a global city. In 2016, Rome ranked as the 14th-most-visited city in the world, 3rd most visited in the European Union, and the most popular tourist attraction in Italy. Its historic centre is listed by UNESCO as a World Heritage Site. The famous Vatican Museums are among the world's most visited museums while the Colosseum was the most popular tourist attraction in world with 7.4 million visitors in 2018. Host city for the 1960 Summer Olympics, Rome is the seat of several specialized agencies of the United Nations, such as the Food and Agriculture Organization (FAO), the World Food Programme (WFP) and the International Fund for Agricultural Development (IFAD). The city also hosts the Secretariat of the Parliamentary Assembly of the Union for the Mediterranean (UfM) as well as the headquarters of many international business companies such as Eni, Enel, TIM, Leonardo S.p.A., and national and international banks such as Unicredit and BNL. Its business district, called EUR, is the base of many companies involved in the oil industry, the pharmaceutical industry, and financial services. Rome is also an important fashion and design centre thanks to renowned international brands centered in the city. Rome's Cinecittà Studios have been the set of many Academy Award–winning movies.
