Sifnos Island was inhabited since the 4th millennia BC and was very wealthy in antiquity thanks to its gold and silver mines. This is proved by the Sifnian Treasury built in Delphi next to the Temple of Apollo. By the 5th century BC the valuable resources of the mines were exhausted and Sifnos fell into decline. But Sifnians found another kind of rich vein on their island, clay. The pottery making became the new economic source and the craft is very popular in Sifnos.
Sifnos spans an area of 73,9 sq. km. with a total population of 2.442 residents. The islands closer to Sifnos are Serifos on the north, Paros and Antiparos on the east, Kimolos and Milos on the southwest.
The settlement of Kastro and the little chapel dedicated to Seven Martyrs on a cliff is a must-see sight. The village is built according to the traditional Cycladic architecture and has extensive medieval remains. Sifnos is popular for the traditional festivities of the churches and chapels all year round. Pottery workshops are spread all over the island of Sifnos and many of the potteries are decorative ornaments of the Sifnian houses.
Sifnos is the birthplace of the famous Greek chef Nikos Tselementes, whose name is almost identical to his cookery book which can be found in every Greek house. Sifnos has a great variety of local specialties like caper salad and revithada a soup made of chickpeas cooked in a clay casserole sealed with pastry so that none of the aromas is lost. Mastelo is the famous local dish of lamp meat cooked with herbs and red wine cooked in a clay pot with the same name.
