İzmit, the capital of Kocaeli Province, is a major city in northwestern Turkey located on the eastern edge of the Marmara Sea. Just a short drive from Istanbul, İzmit is an important industrial and transportation hub, but it also preserves a rich historical legacy dating back to Roman times.
Known in antiquity as Nicomedia, the city was once one of the most important centers of the Roman Empire in Anatolia. Today, İzmit blends its ancient past with modern industry, coastal scenery, museums, and traditional Turkish culture, making it a rewarding stop for both cultural and business travelers.
History
İzmit’s history stretches back more than two millennia. It was founded as Nicomedia in the 4th century BC and later became a major city of the Roman Empire, even serving as an imperial capital during certain periods.
Under the Romans, Nicomedia was a rival to Constantinople in importance and was known for its palaces, baths, aqueducts, and administrative buildings. The city also played a role in early Christian history and later became part of the Byzantine Empire.
After the Ottoman conquest, İzmit developed as a regional center for trade, crafts, and maritime activity. Its strategic location on routes connecting Istanbul to Anatolia ensured continued importance through the centuries.
In the modern era, İzmit has become one of Turkey’s key industrial cities, particularly in petrochemicals, manufacturing, and logistics, while still maintaining cultural and historical landmarks.

- Gulf of İzmit (Izmit Bay)

Its coastal position and access to major highways make it one of Turkey’s most strategically important cities.
