The ancient settlement of Akrotiri on Santorini was buried by the eruption of the Thera volcano sometime between 1620 and 1530 B.C.E., according to the dating generally accepted by scholars. The eruption was among the largest in recorded history, covering the settlement in ash and pumice and preserving buildings, artworks and everyday objects beneath the debris.

Signs of earlier seismic activity may have given residents time to escape. The recovered remains include no known victims of the eruption, suggesting that most or all of Akrotiri’s inhabitants left before the final catastrophe. Archaeological layers of sand and pebbles also point to tsunamis contributing to the damage. The eruption transformed Santorini’s landscape, including when part of the volcanic caldera collapsed into the sea.

The site is often compared with Pompeii because volcanic material preserved it, but Akrotiri reveals a much earlier society. Its location connected it to Crete and the other Cycladic islands, as well as maritime routes linking North Africa, Europe and the Middle East. Evidence from the settlement indicates that its people included farmers, fishers and craftspeople.

Archaeologists have identified 35 buildings, including multistory structures built from volcanic stone, mud, vegetation and limited wood. Many featured paved streets, drainage and indoor plumbing. Frescoes found in homes and public buildings depict subjects including women, crocus flowers and ritual scenes. Pottery, vessels for oil and wine, and charred barley and fava beans have added evidence of trade and daily life.

Modern excavation began on a large scale in 1967 under archaeologist Spyridon Marinatos. Researchers have since explored the site down to bedrock, but estimate that only about 10 percent of the settlement has been excavated. A bioclimatic shelter installed in 2012 protects the fragile ruins, while artifacts from Akrotiri are displayed at the Museum of Prehistoric Thera.

The eruption’s effects on the Minoan civilization of Crete remain debated. Marinatos argued that earthquakes and tsunamis from Thera damaged Minoan buildings and trade, but that explanation is no longer widely accepted as the sole cause of the civilization’s decline. Many historians instead point to several possible factors, including environmental changes, reduced trade, political instability and conflict with the Mycenaeans.

Akrotiri’s preserved remains provide a rare record of a sophisticated, outward-looking Bronze Age community. Excavations are continuing, and Santorini is preparing to mark the 60th anniversary of their official start in 2027 with exhibitions and educational programs.
