Santorini: The Bronze Age City Buried by the Eruption That Shaped the Island

By Travelog Editorial Team · Updated August 10, 2026

Santorini has no UNESCO listing, but its defining feature is genuine and dramatic: a volcanic caldera formed by an eruption around the 17th century BC that buried the Bronze Age settlement of Akrotiri. Greece's Ministry of Culture has excavated Akrotiri continuously since 1967, uncovering an entire city preserved under volcanic ash on the same island where that eruption happened.

Why Santorini's genuine story isn't a UNESCO listing

Unlike every other Travelog city in this pillar, Santorini doesn't carry a UNESCO World Heritage listing. What it does have is genuine and independently documented by Greece's own Ministry of Culture: the Archaeological Site of Akrotiri, one of the most important prehistoric settlements in the Aegean, with its own standalone page below covering current tickets and hours. The earliest structures at Akrotiri date to the Late Neolithic Age, the 4th millennium BC, and by the Early Bronze Age, the 3rd millennium BC, the settlement had grown into a significant commercial and cultural center with genuine trade connections to Minoan Crete, Egypt, and Syria.

The city the eruption buried and preserved

According to the Ministry of Culture, the settlement at Akrotiri was destroyed and buried when the volcano at Thera erupted in the 17th century BC, the same eruption that carved out the caldera Santorini is known for today. That burial is also what preserved the site: the volcanic ash sealed Akrotiri's buildings, frescoes, and artifacts in place. Excavations began in 1967 and continue to this day, uncovering more of the buried Late Cycladic city with each season.

Getting there

Santorini is served by its own airport, with connections from mainland Greece, and by ferry routes from Athens's port of Piraeus and other Aegean islands. Most visitors base themselves in one of the towns along the caldera rim, such as Fira or Oia, and reach Akrotiri, at the island's southern tip, by a short local transit ride or organized tour.

The bottom line

Santorini's genuine story is the eruption that both destroyed and preserved a Bronze Age city, and the caldera that same eruption left behind. Akrotiri is the part of that story you can actually walk through: a genuine excavation, still active, run by Greece's own Ministry of Culture, not a UNESCO plaque but a genuinely significant archaeological site in its own right.
