History
Sile has a fascinating history that stretches back nearly 2,700 years.
The settlement is believed to have been founded during the 7th century BC by sailors from Miletus, one of the great ancient Greek city-states. Owing to its strategic position on the Black Sea coast, Şile soon became an important harbour and trading settlement.
The name Sile is thought to derive from the Greek word referring to a wildflower or aromatic herb, reflecting the area’s rich natural vegetation.
Before the arrival of the Greeks, the region formed part of ancient Bithynia, whose inhabitants were among the earliest known settlers of northwestern Anatolia.
Throughout its long history, Şile came under the control of numerous civilizations, including:
- The Bithynians
- The Lydian Kingdom
- The Achaemenid Persian Empire
- The Galatians
- The Roman Empire
- The Byzantine Empire
- The Latin Empire
- The Seljuk Turks
- The Ottoman Empire
Its coastal location made Sile strategically important for maritime trade and defence. The remains of ancient fortifications, churches, and castles still testify to its historical significance.
During the Ottoman period, Sile developed into a prosperous fishing and agricultural town while also becoming renowned for producing Sile Bezi, a lightweight handwoven cotton fabric that remains one of the district’s most distinctive cultural traditions.
