Whitewashed village on the caldera cliffs of Santorini overlooking the Aegean Sea

Santorini history – A journey through time and myth

Santorini is usually introduced through images: whitewashed villages, blue-domed churches, cliffs and sunsets over the Aegean. Yet the landscape tells a much older story. Long before the island became one of Greece’s most famous destinations, it was shaped by powerful volcanic forces, home to prosperous prehistoric communities and later influenced by different civilizations.

Look closely and that past is still everywhere. It survives in the layers of the caldera, in ancient streets buried for centuries, in hilltop ruins and in fortified villages. Santorini’s history is not separate from the island visitors see today. In many ways, it explains it.

How old is Santorini? The island’s earliest beginnings

So, how old is Santorini?

There is no single birthday to put on the calendar. Santorini belongs to an active volcanic system that has been developing over a very long geological period, while the cliffs of the caldera preserve evidence of major eruptions stretching back tens of thousands of years. The familiar island of today is the result of repeated cycles of volcanic growth, eruption and collapse.

Human history arrived much later. Evidence from Akrotiri shows that people were living on the island by at least the Late Neolithic period, while a substantial settlement developed there during the Early Bronze Age.

Thanks to its position in the southern Aegean, ancient Thera became connected to wider trade networks. By the second millennium BC, its communities were part of a busy maritime world linking the Cyclades with Crete and the eastern Mediterranean.

The volcano that changed Santorini forever

Then came the event that changed almost everything. During the Late Bronze Age, around the middle of the second millennium BC, Santorini experienced an enormous eruption, often called the Minoan or Thera eruption. Vast quantities of volcanic material were released, while the collapse associated with the eruption helped form the dramatic caldera that defines Santorini today.

Its effects reached far beyond the island. Ash and volcanic deposits spread across the region, while tsunamis affected parts of the Aegean. On Santorini itself, the settlement of Akrotiri was buried beneath ash and pumice. Strangely enough, the same catastrophe that ended life there also preserved buildings, objects and wall paintings for archaeologists to uncover thousands of years later.

And what about Atlantis? Santorini has often been linked to Plato’s story of a wealthy island civilization destroyed by catastrophe. The similarities have inspired countless theories, especially because of the eruption and the sophisticated society revealed at Akrotiri. Still, there is no proof that Santorini was Atlantis. The connection remains one of those fascinating places where history, archaeology and myth meet.

 

Santorini history and culture – A heritage still alive today

The Bronze Age eruption was not the end of Santorini’s story. Centuries later, Dorian settlers founded Ancient Thera on Mesa Vouno, and the island continued to develop through the Greek, Roman, Byzantine and medieval periods. Each era left something behind, from archaeological remains to fortified settlements and religious monuments.

Today, many of those layers can still be explored in person. Rather than thinking of Santorini historical sites as separate attractions, it helps to see them as chapters of the same story.

Akrotiri archaeological site

Akrotiri offers the clearest window into prehistoric Santorini. The settlement developed into an important Aegean urban center and port, with substantial buildings, streets, and evidence of organized daily life and trade. When excavations brought it back to light, archaeologists found a place remarkably preserved beneath volcanic material.

What makes a visit so memorable is the level of detail. Multi-story buildings, storage vessels, household objects, and sophisticated frescoes reveal how people lived and decorated their surroundings more than three millennia ago. Suddenly, the Bronze Age does not feel quite so distant.

Ancient Thera

For a completely different period, head to Ancient Thera. Founded by Dorian colonists in the 9th century BC, the city occupies Mesa Vouno, almost 400 meters above sea level. Its position was strategic, but the views are impressive too.

The remains include streets, sanctuaries, public buildings and later Christian monuments, reflecting the city’s long development through different eras. Where Akrotiri introduces prehistoric Santorini, Ancient Thera shows how the island re-emerged in the historic Greek and Roman world.

Vlychada is the beach to choose when the scenery matters just as much as the swim. Its tall, pale cliffs have been shaped by wind and erosion into unusual formations, giving the coastline an almost lunar appearance.

The beach is about 13 km from Fira and is easily reached by car, with parking available near the shore. Seasonal buses also connect Fira with Vlychada, although the stop may require a short walk.

The main section has loungers, umbrellas, and a café or beach bar, but the atmosphere becomes quieter as you continue along the coast. Near the small marina, you will also find restaurants where you can enjoy fresh fish and local dishes after swimming. Compared with Kamari and Perissa, Vlychada feels less commercial and leaves much more room for a peaceful afternoon by the sea.

Pyrgos and the Venetian Castle

Santorini’s medieval past becomes much more visible in Pyrgos. The village developed around a Venetian castle, with narrow passages, tightly packed houses and an elevated position that helped residents defend themselves during less peaceful centuries.

The Castle of Pyrgos dates to around 1580 and is considered the newest of Santorini’s fortified castle settlements. Today, walking through the village feels less like entering an archaeological site and more like moving through a place where medieval planning is still part of everyday island life.

Skaros Rock

Rising in front of Imerovigli, Skaros Rock is one of Santorini’s most recognizable landmarks, but its importance is not only geological. During the medieval period, the area became an important fortified center because of its naturally defensive position above the caldera.

Much of the old settlement has disappeared, yet the walk towards Skaros makes its strategic value easy to understand. The steep terrain and wide views over the sea tell their own story. It is also a direct link between Imerovigli’s calm present and a time when protection and visibility were essential.

Experience Santorini’s history in the present

Perhaps the best way to experience Santorini is to move between these different layers. Spend a morning among the remains of Akrotiri, wander through Pyrgos later in the day, then look across the caldera and remember that the landscape itself is part of the island’s history. Few destinations bring geology, archaeology and everyday life together so naturally.

Pegasus Suites & Spa offers a fitting base for that journey. Located in Imerovigli, just 1.5 km from Fira, the hotel looks out towards the caldera, the volcano and the Aegean, while Skaros Rock is close at hand. Its suites are designed around privacy and comfort, with private terraces and, in many cases, private pools or outdoor Jacuzzis overlooking the caldera.

And after history, there is time for everything else Santorini does so well. Guests can unwind with face and body treatments or the indoor heated pool with Jacuzzi at Pegasus Heaven Spa, enjoy Greek-inspired dining and local wines, or simply settle into the slower rhythm of the island. Breakfast can mark the beginning of another day of exploring, while the hotel’s gastronomy draws on Greek flavors, fresh ingredients and Santorini’s wine culture.

The island has taken thousands of years to become what it is today. There is no reason to rush through it.
