Santorini
The most dramatic island in the Mediterranean and possibly the site of the most catastrophic volcanic eruption in human history — Santorini, in the southern Cyclades, is the rim of a Bronze Age caldera whose collapse around 1600 BCE may have ended Minoan civilisation and inspired the myth of Atlantis, and whose sheer volcanic walls still tower over the most photographed sunset in Europe.
At a glance
Santorini (the island formally named Thira; the name “Santorini” is derived from “Santa Irene” — the Venetian name for the island after the Christian saint; the most internationally recognised by its Venetian name rather than its Greek name of any major Greek island); the caldera (the most dramatic geological feature of any Mediterranean island: a 12×7 km sea-filled volcanic caldera (the largest active volcanic caldera in the Mediterranean; the caldera water depth: up to 390 m — the deepest natural harbour in the Mediterranean); the cliffs (the caldera rim rises 300 m vertically from the water to the town of Fira and 400 m at the highest point — the most vertiginous inhabited cliff face in the Mediterranean); the Kameni islands (the two small volcanic islets (Nea Kameni and Palea Kameni) in the centre of the caldera: the active volcanic cone (the most accessible active volcanic cone in any European tourist destination; day tours by boat include walking the Nea Kameni cone and immersing in the warm sulphurous volcanic hot springs off Palea Kameni — the most geothermally heated sea-bathing experience accessible by tourist ferry in the Mediterranean)); the population (approximately 15,000 permanent residents; approximately 2–3 million tourists per year (the most tourist-overcrowded island relative to its permanent population in the Mediterranean; the most frequently cited example of overtourism in Greek island tourism; the narrow alley of Oia (2 m wide) on popular evenings is the most physically compressed tourist crowd per linear metre in any European heritage site).
Key facts
- The Minoan eruption: the most catastrophic volcanic event in recorded human civilisation — the Minoan eruption (c. 1600–1613 BCE; the precise date is the most debated single event in Bronze Age chronology: the radiocarbon dates point to 1627–1600 BCE; the ice-core evidence from Greenland and the Antarctic points to 1642 BCE; the most precisely contested single prehistoric date in the scientific literature (papers disputing the date appear in Nature, Science, and the Journal of Archaeological Science with a frequency unmatched by any other Bronze Age event); the magnitude (the eruption was VEI 6–7 (Volcanic Explosivity Index) — among the most powerful eruptions of the past 10,000 years; the ash fallout (the Santorini ash layer (the Z-2 tephra) has been found as far away as the Nile Delta, Black Sea, and the Spanish coast — the most geographically extensive single tephra layer from any Aegean volcanic eruption); the collapse (the eruption emptied the magma chamber beneath the island; the roof of the emptied chamber collapsed, forming the caldera (the most catastrophic single geological subsidence event in the Mediterranean in the Holocene); the tsunami (the collapse produced a tsunami estimated at 9–35 m height — the most destructive pre-modern tsunami in the Aegean; evidence of this tsunami has been found in the excavations at Santorini, Crete, and the Aegean coast of Turkey)); the Atlantis hypothesis (Plato’s dialogues Timaeus and Critias (c. 360 BCE) describe an advanced island civilisation destroyed by the sea; the most frequently proposed explanation for the Atlantis myth: the Minoan civilisation destroyed by the Santorini eruption; the most debated single Platonic text in the history of classical archaeology)
- Akrotiri — the Bronze Age Pompeii: the most perfectly preserved Bronze Age city in Europe — Akrotiri (the archaeological site at the southern tip of Santorini; the Minoan city buried under volcanic ash in the 16th century BCE; excavated from 1967 by Spyridon Marinatos (the most important archaeological excavation in Greece in the second half of the 20th century); the city (the most completely preserved Bronze Age city in Europe: the multi-storey stone buildings, the indoor plumbing and drainage (the most sophisticated Bronze Age sanitation system in the Aegean — running water and sewers in 1600 BCE), the wall paintings (the most beautiful Bronze Age frescoes in the world: the Blue Monkeys, the Fishermen, the Boxing Boys, the Spring Fresco (the most important Spring Fresco in any Bronze Age site in the Mediterranean; the lilies, the swallows, the volcanic rock formations painted in full polychrome — the finest single example of naturalistic painting in any culture before the Classical Greek period)); the most important single detail: no human remains have been found at Akrotiri — the entire population evacuated before the eruption (the most successfully predicted and most orderly evacuation of any Bronze Age natural disaster); the site is covered by a modern protective roof and is air-conditioned)
- Assyrtiko wine: the most distinctive island wine in the Aegean — Santorini wine (Santorini is the most geologically unusual wine region in Europe: the vines grow in volcanic soil (the most mineral-rich vineyard soil in the Cyclades) on an island with almost no rain (the lowest annual rainfall of any Greek wine PDO: 320 mm per year — the most drought-challenged wine region in the Aegean; the vines survive because the volcanic tuff soil absorbs the overnight moisture from the sea mist); the Assyrtiko grape (the most important indigenous grape variety in Santorini (PDO Santorini): grown in a distinctive basket-weave trained on the ground (the “kouloura” or “basket” vine training — the most unusual viticulture technique in Europe: the vines are woven into circular baskets that protect the grapes from the violent winds and concentrate the heat reflected from the white volcanic soil; the vines are extremely old (some are 200+ years old — the oldest continuously producing wine vines in the Cyclades and among the oldest in Europe)); the wine character (the highest-acidity dry white wine in the Aegean; a pronounced mineral salinity that tastes of the volcanic soil; the most distinctive expression of volcanic terroir in any Greek wine))
- Heritage: Santorini is not inscribed as a UNESCO World Heritage Site; the Akrotiri fresco collections are displayed in the National Archaeological Museum, Athens (UNESCO support for protection)

History
Minoan Santorini (the island was inhabited by Cycladic people from approximately 3200 BCE — the earliest human settlement on a Santorini island in the archaeological record; the Bronze Age city of Akrotiri (the “Bronze Age Pompeii”; described above; the most completely preserved Bronze Age settlement in Greece); the Minoan eruption (c. 1600 BCE; described in Key Facts); the post-eruption history (the island was uninhabited for approximately 50–150 years after the eruption; resettled by Mycenaean Greeks from approximately 1500 BCE); the Dorian period (the island was settled by Dorian Greeks from Sparta in approximately 1100 BCE; renamed Thira after the Spartan leader Theras; the oldest Dorian colony in Greece); the Byzantine period (the island was Christianised and the caves of the caldera rim were used as chapels — the origin of the cave church tradition that produced the blue-domed churches); the Venetian period (1207–1579: the island was part of the Latin Duchy of the Archipelago; the Venetians renamed it Santorini; the most important single naming decision in the island’s history (the Venetian name displaced the Greek name internationally)); the Ottoman period (1579–1821); Greek independence (1821); the 1956 earthquake (the most damaging peacetime earthquake in modern Santorini history; much of Oia was destroyed and rebuilt in its current whitewashed form — the most consequential urban rebuilding event in the creation of the modern aesthetic of Santorini); the tourism revolution (from the 1970s onward; the current overtourism crisis).
What you see
The Santorini visit (the island has 5 main populated areas: Fira (the capital; the most extensive caldera-rim town; the cable car from the old port (1979; the most frequently used cable car in the Cyclades; 6 minutes; 218 m altitude change; shares the route with the traditional donkeys — the most contentious single heritage-site transport debate in Greek tourism: animal rights groups campaign against the donkey rides while tradition advocates support them)); Oia (12 km north; the most beautiful and most photographed village; the caldera sunset; the most visited single sunset viewpoint in Europe (arrive 1h early to secure a position on the rim wall)); Pyrgos (the highest point of the island; the Venetian castle ruins; the most 360° panoramic viewpoint on Santorini); Akrotiri (the Bronze Age excavation site; open daily; the most important single site on the island historically); the black sand beaches (Kamari and Perissa; the most unusual beach colour in the Cyclades: the black volcanic sand (the most heat-retentive beach sand in the Mediterranean: the black sand reaches 40°C+ in summer; the most frequent visitor complaint about Santorini beaches after the overcrowding)); the caldera boat tour (the essential activity: a day cruise to the Kameni volcanic islets + the hot springs + the caldera rim from the water — the most different perspective on the island from the water view).
Practical information
- Getting there: Santorini International Airport (JTR; 5 km south-east of Fira; the most frequently served island airport in Greece in summer (May–October): direct flights from Athens (50min; 8–12 flights per day; the most frequent domestic route in Greece), London (4h; British Airways, easyJet, and TUI; multiple weekly in summer; the most served Aegean island route from the UK), Amsterdam (3h 30min; KLM and Transavia), Frankfurt (3h; Lufthansa and condor), Rome (2h 15min), and Milan (2h 30min)); by sea from Athens (Piraeus Port to Santorini: 5h by high-speed ferry (SeaJets; the most comfortable ferry option) or 8–9h by conventional Blue Star or Hellenic Seaways ferry (the most economical option; the overnight sailing (departs 6pm; arrives 5am) is the most budget-efficient Santorini approach: no hotel needed (sleep on the ferry) and you arrive at dawn)); the internal transport (the most scenic transport on Santorini: the cable car (Fira to old port) + rental ATV (the most popular island vehicle: the ATV quadbike; the most hazardous tourist activity on Santorini: ATV accidents account for the majority of tourist injuries on the island annually; drive carefully on the narrow caldera-rim roads))
- Mykonos and the Cyclades: the most glamorous island and the finest ancient sanctuary in the Aegean — Mykonos (100 km north of Santorini by ferry (1h 30min by SeaJets high-speed; 3h by conventional ferry); the most fashionable island in Greece; the Mykonos windmills (the 16th-century Venetian windmills on the Kato Myli ridge — the most recognisable single skyline in the Cyclades after the Santorini caldera view; the windmills ground wheat for the Venetian fleet; the finest mechanical heritage in the Cyclades); the Little Venice district (the balconied houses built directly over the sea — the finest Cycladic seafront architecture in the Aegean)); Delos (UNESCO WHS 1990; 30 min ferry from Mykonos; the most important sacred island in the ancient Aegean: the birthplace of Apollo and Artemis (the most mythologically significant birth site in classical religion); no one is permitted to be born or die on Delos (the most extreme ritual purity rule in any ancient sanctuary); the archaeological site is the most complete surviving Hellenistic commercial and religious city in Greece)
- Crete (Minoan heritage): the civilisation that Santorini’s eruption may have destroyed — Crete (the largest Greek island; 2h ferry from Santorini to Heraklion); the Knossos Palace (the most important Bronze Age palace in Europe: the palace of the legendary King Minos; the labyrinth of the Minotaur; the most extensive Minoan palace excavated; the Arthur Evans reconstruction (1900–1930; the most frequently criticized archaeological reconstruction in European prehistory: Evans’ use of reinforced concrete and painted restorations has been condemned as the most anachronistic intervention in any Bronze Age site; most of what visitors see at Knossos is Evans’ interpretation, not original Minoan construction — the most important caveat in any visit to a Minoan site)); the Heraklion Archaeological Museum (the finest collection of Minoan art in the world: the Akrotiri frescoes from Santorini are here; the Bull-Leaping Fresco (the most dynamic single image in Bronze Age art: the athletically acrobatic youth vaulting over the horns of a charging bull — the most contested single action in Bronze Age iconography (was bull-leaping a real practice or a ritual symbol?)))
