ギリシャ

Greece, officially the Hellenic Republic, occupies the southern extremity of the Balkan Peninsula in Southeast Europe. Encompassing approximately 131,957 square kilometres of land and more than 10 million inhabitants, it shares borders with Albania to the northwest, North Macedonia and Bulgaria to the north, and Turkey to the east. Bordered by the Ionian Sea on the west, the Aegean Sea on the east, and the Mediterranean (including the Sea of Crete) to the south, Greece’s territory includes a highly indented mainland coastline of some 13,676 kilometres and thousands of islands, 227 of which support permanent settlements. The nation’s nine traditional geographic regions extend from the rugged Pindus range in the west to the fertile plains of Thessaly, and from the Rhodope massifs in the northeast to the Peloponnese peninsula in the south. Athens, the capital and largest city, anchors the Attica region, followed in size and commercial importance by Thessaloniki and Patras.

Greece’s distinctive peninsular form—jutting toward the Mediterranean crossroads of Europe, Asia and Africa—has shaped its natural and human history. The Isthmus of Corinth separates the mainland from the Peloponnese, while extreme geographical points mark the village of Ormenio in the north, the island of Gavdos in the south (the southernmost point of Europe), Strongyli near Kastellorizo to the east, and Othonoi in the Ionian Sea to the west. Roughly 80 per cent of its terrain is mountainous or hilly, among the highest proportions in Europe. Mount Olympus, mythic home of the Olympian deities, reaches 2,918 metres at its Mytikas summit; the Pindus range, a westward extension of the Dinaric Alps, rises to 2,637 metres at Mt. Smolikas and has historically hindered east–west passage. In Epirus, the Vikos Gorge—within the Pindus massif—claims distinction as the world’s deepest gorge, while the towering rock pillars of Meteora support centuries-old Orthodox monasteries. The Rhodope range dominates Eastern Macedonia and Thrace, its ancient woodlands prolonging to the Dadia Forest. In contrast, the alluvial plains of Thessaly, Central Macedonia and Thrace provide the nation’s principal arable lands.

Island clusters define the maritime character of Greece. Crete—the largest and fifth-largest Mediterranean island—leads in both size and population, with Euboea, Lesbos and Rhodes following. Traditional groupings include the Argo-Saronic Islands near Athens, the Cyclades at the heart of the Aegean, the Dodecanese southeast of Rhodes, the Sporades off northeast Euboea, the North Aegean islands near Turkey’s west coast, and the Ionian Islands along the mainland’s western flank. Depending on criteria, between 1,200 and 6,000 islands exist within Greek waters, though fewer than 250 are inhabited.

Greece’s climate is predominantly Mediterranean (Köppen Csa), characterized by mild, wet winters and hot, arid summers along most coasts, including Athens, the islands of Crete and the Cyclades, and the southern mainland. The Pindus barrier creates a rain-shadow effect: western slopes receive higher precipitation from south-westerly systems, while leeward eastern areas can approach semi-arid (BSh) conditions, notably along the Athens Riviera and select Cycladic isles. Northern latitudes around Thessaloniki and Larissa exhibit a cold semi-arid (BSk) climate. Alpine (D/E) conditions prevail in high elevations of Epirus, Thessaly and central Peloponnese, with heavy winter snow, while humid subtropical (Cfa) regimes, marked by cold, damp winters and hot, storm-prone summers, extend across northern lowlands. Sporadic snow may even descend on lowland Athens during particularly severe cold spells.

The narrative of Greece unfolds as the cradle of Western civilisation. Between the eighth and fourth centuries BC, independent city-states—or poleis—such as Athens, Sparta, Corinth and Thebes flourished, laying the foundations of democracy, philosophy, historiography, theatre, political science and mathematics. In the mid-fourth century BC, Philip II of Macedon united the disparate Greek polities; his son, Alexander the Great, rapidly extended Hellenic culture from the eastern Mediterranean across Anatolia, Egypt, Persia and into northwestern India. The ensuing Hellenistic era represented the apogee of Greek cultural influence. Rome’s annexation in the second century BC folded Greece into the Roman Empire, and later into the Byzantine Empire, whose predominantly Greek language and traditions preserved classical heritage. The Greek Orthodox Church, sprouting during the first century AD, became integral to national identity and disseminated Byzantine culture throughout Orthodox lands. After the Fourth Crusade in 1204, Latin states seized portions of the peninsula; by the mid-15th century, Ottoman rule prevailed until the early 19th century.

The modern Greek state emerged from a protracted revolutionary struggle, beginning in 1821 and culminating in international recognition of independence in 1830. The Kingdom of Greece expanded its territory during the Balkan Wars (1912–13) and into western Anatolia, only to suffer a calamitous defeat against Turkish forces in the Asia-Minor Campaign of 1922. A republic briefly took hold in 1924 but succumbed to authoritarianism in 1936, setting the stage for Axis occupation in World War II, a subsequent civil war, and military junta from 1967 to 1974. Restoration of civilian rule in 1974–75 inaugurated the present parliamentary republic.

Economically, Greece achieved sustained growth from the 1950s through the 1970s. Today it is classified as a high-income, advanced economy—the 54th largest by purchasing power parity at approximately USD 417 billion and the 15th largest within the European Union. In 1981 Greece became the tenth member of what is now the European Union and participates in numerous international organisations. Tourism and maritime transport are pillars of the national economy. In 2023 Greece ranked ninth among the world’s most-visited countries, welcoming over 28 million international arrivals. The nation boasts 19 UNESCO World Heritage Sites, with another 13 on the tentative list.

Deeply rooted in its seafaring tradition, Greece’s shipping industry contributes some 5 per cent of GDP and employs roughly 160,000 persons. The Greek Merchant Navy commands 18 per cent of global capacity, ranking first in tonnage (384 million deadweight tonnes), second in vessel count (4,870), first in tankers and dry bulk carriers, fourth in container ships and fifth in other vessels. The flag-state fleet comprises 1,517 ships, representing 5 per cent of world tonnage. Shipbuilding and repair remain robust around Piraeus, where six major shipyards stand among Europe’s largest, and Greece has emerged as a centre for luxury yacht construction.

Overland transport infrastructure has modernised markedly since the 1980s. By 2020 Greece possessed some 2,320 kilometres of motorways—the most extensive such network in Southeast Europe—including the A1 (Athens–Thessaloniki), the east–west A2 (Egnatia Odos), and the A5 (Ionia Odos), which links the Rio–Antirrio suspension bridge (Europe’s longest at 2,250 metres) to the western coast. The privately operated Attiki Odos encircles greater Athens, complementing the expanded Athens Metro; Thessaloniki’s metro commenced operations in 2024. Rail lines, totaling approximately 2,500 kilometres, support intercity, suburban and international services, with ongoing upgrades to double-track standard gauge between Athens and Patras and elsewhere. Maritime connections remain vital: Piraeus was Europe’s third-busiest passenger port in 2021, and nearly 37 million passengers traversed Greece’s ferry network in 2019. Air travel has grown in parallel: among 39 active airports (15 international), Athens International handled more than 28 million passengers in 2023, while Aegean Airlines, Olympic Air and Sky Express link the capital with islands and global destinations.

Demographically, Greece’s population stood at an estimated 10.6 million in 2022. Fertility has declined from 5.5 children per woman in 1900 to around 1.4 today, well below the replacement threshold of 2.1, driving median age upward to 44.2 years—among the highest worldwide. Between 1981 and 2016, the birth rate fell from 14.5 to 8.5 per thousand, while mortality rose from 8.9 to 11.2 per thousand. By 2016, persons aged 65 or older comprised 21 per cent of the populace, versus roughly 14 per cent under age 15. Marriage rates declined from 71 to 51 per thousand between 1981 and 2004, and divorces increased from 191 to 240 per thousand marriages. Economic contraction since 2010 propelled some 350,000 to 450,000 primarily young Greeks to emigrate.

The Greek Constitution recognises Eastern Orthodoxy as the prevailing faith, and while religious affiliation is not enumerated in censuses, an estimated 97 per cent of citizens identify as Greek Orthodox, under the jurisdictions of the autocephalous Church of Greece and the Ecumenical Patriarchate of Constantinople.

Greece’s cultural patrimony underpins its appeal. In Athens, the Parthenon and Acropolis testify to fifth-century BC civic achievement; Delphi’s sanctuary of Apollo once guided Hellenic consultation with the divine; and the temple of Apollo at Bassae emerges inconspicuously amid Arcadian hills. The medieval old city of Rhodes preserves the legacy of the Knights Hospitaller, while Olympia’s stadium evokes the birth of the Olympic Games. In northern Greece, the tumulus tombs of Vergina—among them that of Philip II—connect visitors to the dawn of Macedonian hegemony. Mystras, perched on Mount Taygetos, recalls Byzantine splendour near ancient Sparta, and Delos, sacred birthplace of Apollo and Artemis, remains studded with Hellenistic remains.

Island sites marry archaeological discovery with coastal allure. Patmos showcases the Monastery of Saint John and the Cave of the Apocalypse alongside tavernas on inviting shores. Corfu’s Venetian-flavoured architecture complements Ionian beaches; Samos offers ancient wines, the temple of Hera and the Eupalinos Tunnel; and Mount Athos, a monastic republic on Chalkidiki’s Athos peninsula, restricts tourist access but rewards pilgrims with Byzantine frescoes. Mainland treasures include Epidaurus’s sanctuary of Asclepius and the Mycenaean citadels of Mycenae and Tiryns. Other World Heritage monastic sites—Daphni near Athens, Hosios Loukas in Boeotia and Nea Moni on Chios—attest to Byzantine piety.

Nature and adventure travel have flourished. Crete’s gorges, Epirus’s national parks and Mount Olympus draw hikers; sailboats set course among more than 1,400 isles, from the temperate Ionian waters ideal for novices to the Meltemi winds of the Cyclades that challenge seasoned skippers. White-sand beaches along the mainland coasts of Chalkidiki, Epirus and the Peloponnese complement island resorts on Crete, Rhodes, Kos and Zakynthos—where the National Marine Park protects loggerhead turtles. Adventure-sport enthusiasts find kitesurfing, rafting and canyoning in mountainous river valleys. Pilgrims trace the Via Egnatia or climb to medieval monasteries on cliff faces.

Visitors encounter Greek society’s hallmark warmth and informality. Politeness is measured in conduct rather than overly ceremonious speech; a simple greeting often initiates genuine hospitality. Greeks employ expressive hand gestures and readily engage in small talk, sometimes to the accompaniment of raki at a village kafeneion. Proper deference in ecclesiastical settings—covered shoulders or knees—respects local custom, although tourist influx softens enforcement during high season. Nudism remains largely confined to designated beaches on Crete, Rhodes, Kefalonia and Zakynthos; elsewhere, topless or nude sunbathing may occasion discomfort among locals.

Administratively, Greece comprises 13 regions—ranging from the Peloponnese and Central Greece to Thessaly, Northern Greece, Epirus, Crete and the island clusters—and 74 regional units. Major urban centres beyond Athens, Thessaloniki and Patras include Heraklion, Chania, Kavala, Volos and Rhodes, each offering a blend of historical sites and modern amenities. Visitors rely on the euro, navigate right-hand traffic, and access emergency services via European-standard numbers (112 for general emergencies) within the UTC +2 time zone.

As the birthplace of democracy and Western thought, Greece sustains a profound legacy in politics, philosophy and the arts. Its landscapes—from snow-capped summits and fertile plains to crystalline seas and storied ruins—continue to inspire travellers. Whether exploring antiquity’s monuments, sailing azure archipelagos or savouring age-old customs in mountain villages, visitors encounter a nation where past and present converge in enduring harmony.

In sum, Greece offers an unparalleled synthesis of natural grandeur, historical depth and cultural vitality. It remains a land where the footsteps of ancient philosophers intersect with the rhythms of modern life, inviting travellers to partake in a journey across time and terrain that is as enlightening as it is unforgettable.
