During antiquity, Sifnos was known under the name of Meropi. It was the wealthiest island of the Cyclades and was inhabited by the Iones.
In Delphi, one can currently find the treasures of the Sifnians that are only a sample of the island's wealth. As a member of the Athenian Alliance, Sifnos aided the Athenians during the war against the Persians. During the Franks rule in the Aegean, Sifnos came under the occupation of several families. In 1573, the Turks took over occupancy from the Venetians, but the island was still allowed many privileges. Poets, important names of the Greek intelligentsia, playwrights, renowned jurists/legists and Constantinople's Patriarch Gregorios the 7th, were born in Sifnos. Other famous personalities born on the island include the great doctor of antiquity Difilos, during the 3rd century and during the 19th century, the famous cook Nikolaos Tselementes, a man who was influenced and who himself influenced the well-known and interesting to our days, Sifnian cuisine.
The main town, near the center, known as Apollonia, is home of the island's folklore museum and library. The town's name is thought to come from an ancient temple of Apollo on the site of the church of Panayia Yeraniofora. The second-largest town is Artemonas (800), thought to be named after an ancient temple of Apollo's sister-goddess Artemis, located at the site of the church of Panayia Kokhi. The village of Kastro (118), built on top of a high cliff on the island's northwestern shore on the site of the ancient city of Siphnos, today has extensive medieval remains and is the location of the island's archeological museum. The port settlement, on the west coast of the island is known as Kamares.
