Akrotiri site, the city beneath the ash

What it is

Akrotiri is a Bronze Age city that the eruption of the Santorini volcano buried under ash, probably in the late 17th century BC. It was inhabited from about 4500 BC and became one of the great centres of the prehistoric Aegean, with sea trade and copper workshops. An earthquake shook it shortly before the eruption, and its inhabitants seem to have left in time: hardly any gold objects have been found and no unburied body.

The ash preserved it like few others. It has been excavated since 1967, first by Spyridon Marinatos and then by Christos Doumas. Today you see paved streets and drainage, squares and more than 30 multi-storey buildings.

What you will see

The whole site is under a large bioclimatic roof, so you visit in the shade. You walk along walkways following a fixed route, with stops to look from above and from street level. Look out for:

• Xeste 3, the best-studied public building, linked to rites of passage, with its stone staircase to the first floor.
• The West House, a three-storey dwelling next to the Triangular Square, from which frescoes came from two rooms on the second floor.
• The jars and vessels still in place, and the stairs and stone door jambs, which give an idea of the height of the houses.
• The furniture casts: archaeologists filled with plaster the hollows that the wood left in the ash.

The frescoes aren't here. Those displayed on the island are in the Museum of Prehistoric Thera, in Fira: it opens from 8:30 to 15:30, closes on Tuesdays and costs €10 (€5 reduced). The Spring Fresco is in the National Archaeological Museum in Athens. Seeing the museum before or after gives the visit meaning.

Opening hours

According to the Ephorate of Antiquities of the Cyclades, for 2026:

• From 1 November to 31 March: from 8:30 to 15:30; closed on Tuesdays.
• From April to October: Mondays and Thursdays, from 8:30 to 15:30; the other days, from 8:00 to 18:00. In September and October closing time on those days gets later: until 19:30 in the first half of September, 19:00 in the second, 18:30 in the first half of October and 18:00 in the second.

The last entry is 20 minutes before closing. It is closed all day on 1 January, 25 March, Orthodox Easter Sunday, 1 May and 25 and 26 December.

Tickets

General admission costs €20 and reduced €10. It is bought at the ticket office or online on the Greek Ministry of Culture's ticketing website, linked from the Ephorate's page. In July and August, having it bought in advance saves you the ticket-office queue.

There are no official guided tours included in the ticket. The Ephorate's page offers a downloadable guide in English and Greek. If you want a guide, hire one separately through an agency or an official guide.

How to get there and how long it takes

The site is on the south-west coast, next to the village of Akrotiri. The KTEL bus leaves from Fira station and costs €2.20 (€2.80 at night, from 0:30 to 5:00). By hire car or quad you get there quickly from Fira along the southern road.

Allow an hour and a half for an unhurried visit. If you add the Fira museum, reserve half a day.

With children and accessibility

Being covered and with walkways, it is a comfortable visit in the heat and suitable for children from about 6, who understand well the idea of a city covered by a volcano. The official page doesn't detail accessibility; the walkways have sloping stretches, so with a wheelchair or pushchair ask at the ticket office on arrival.

How to combine it

About 300 m below the site is Akrotiri beach, the starting point for the sea kayak along the south coast, and Red Beach is nearby. In the afternoon you can go up to Pyrgos for the sunset.
