The History of Sifnos
Written by Elena Philippou,Updated June 2026
How a quiet Cycladic island was once the richest in the Aegean.
Sifnos looks like a peaceful place to do very little, and it is. But its past is anything but quiet. This small island was once among the wealthiest in the Aegean, and its story runs through gold, marble, clay and food, much of which you can still see and taste today.
The richest island in the Aegean
In antiquity Sifnos was famous for its wealth. Gold, silver and lead were mined here from as early as the third millennium BC, and the historian Herodotus called the Siphnians the richest of all the islanders. The old workings (at Agios Sostis on the east coast, among others) can still be made out, slowly being reclaimed by the sea.
The Treasury of the Siphnians at Delphi
With that wealth, around 525 BC, the Siphnians built one of the most beautiful structures of the ancient Greek world: their Treasury at Delphi, on the Sacred Way to the sanctuary of Apollo. It was among the first buildings made entirely of marble, richly carved with a frieze of gods and battles, and paid for from a tithe (a tenth) of the island's mining income. The frieze survives in the Delphi museum. Legend has it that when the Siphnians grew greedy and stopped sending Apollo his share, the sea broke in and flooded the mines.
Three thousand years of clay
Long after the gold ran out, the island's clay kept it working. Sifniot pottery reaches back to antiquity (Geometric-era pieces sit in the Kastro museum), and by the nineteenth century coastal workshops in Kamares, Faros, Platis Gialos and Vathi were exporting tableware and cooking pots across Greece and the Mediterranean. That clay pot is also why the island cooks the way it does.
More on the Sifnos pottery traditionThe island that taught Greece to cook
Sifnos is the gastronomic capital of the Cyclades, and it gave Greece its most famous chef. Nikolaos Tselementes was born in the village of Exambela in 1878; his 1910 cookbook was so influential that 'Tselementes' became the Greek word for a cookbook. The island's slow-cooked signatures, revithada (chickpeas) and mastelo (lamb or goat in wine), are still cooked in the local clay, the two traditions feeding each other.

For its size, Sifnos has more churches and chapels than any other Cycladic island — well over two hundred. Many were built by families as private vows, and the Archdiocese of Sifnos dates to 1646. The island's patron is Panagia Chrysopigi, whose monastery on its little headland was founded in 1523; her festival on the eve of Ascension Day still draws pilgrims from across the island.
Festivals & experiences in SifnosKastro, the medieval capital
Through the medieval and Venetian centuries the island's capital was Kastro, the fortified village on the east coast, where coats of arms are still set above old doorways. Older still is the acropolis at Agios Andreas, a fortified hilltop settlement with a small museum, looking out over the island's centre.

You don't have to go far to touch all this. Walk the lanes of Kastro and its archaeological museum, climb to the acropolis at Agios Andreas, visit Chrysopigi at the water's edge, and step into a working pottery studio — the same craft, still turning.
The history of Sifnos — common questions
Why was Sifnos so rich in ancient times?
Sifnos had gold, silver and lead mines, worked from the third millennium BC. Herodotus called the Siphnians the richest of the islanders — wealth they famously spent on their marble Treasury at Delphi.
What is the Treasury of the Siphnians?
A small marble treasury the Siphnians built at Delphi around 525 BC, on the Sacred Way to Apollo's sanctuary, paid for from a tithe of their mining income. Its carved frieze is one of the masterpieces of Archaic Greek sculpture, now in the Delphi museum.
Why is Sifnos famous for pottery and food?
Sifnos has made pottery for some 3,000 years, and the local clay pot shaped its cooking — slow dishes like revithada and mastelo. It's considered the gastronomic capital of the Cyclades, and gave Greece its most famous chef, Nikolaos Tselementes.
Can you see Sifnos's history today?
Yes — visit the medieval village of Kastro and its archaeological museum, the ancient acropolis at Agios Andreas, the monastery of Chrysopigi, and the island's working pottery studios.
