Kocaeli Guide

Kocaeli, the third-largest city in the Marmara Region, is widely known by the name of its central district, İzmit. As a key hub for industry, trade, and economy, the city plays a crucial role in the region. Thanks to its proximity to major cities like Istanbul and Bursa, Kocaeli is a dynamic center for history, tourism, and culture, welcoming numerous visitors each year. Strategically positioned at a crossroads between Asia and Europe, Kocaeli sits along important trade routes, while İzmit Bay remains one of Turkey's busiest commercial and industrial ports.

Beyond its industrial and commercial significance, Kocaeli is also a city of history, sea, and natural beauty. A historic district featuring old Ottoman houses has been fully restored and opened to tourism, offering visitors a chance to explore century-old plane trees and charming streets. Additionally, being a coastal city, Kocaeli enjoys the advantage of seaside districts, where locals often spend their summers by the sea or lakes, even though it is not widely known for beach tourism.

One of the most famous tourist attractions in Kocaeli is Lake Sapanca. Although the lake is mainly within the Sakarya province, it also extends into Kocaeli. A natural wonder, the lake offers breathtaking views that change with each season, making it a perfect destination for nature lovers.

Kocaeli experiences a continental climate, with traces of the Black Sea climate in some areas. Winters are cold and rainy, while summers tend to be hot and humid.

A City with a Rich History

Kocaeli has been a settlement area for thousands of years, with archaeological evidence dating back to 3000 BC. The city’s recorded history began around 700 BC, when migrating tribes from Europe settled in the region, as revealed by archaeological excavations. Later, it became a part of the Bithynian Kingdom, under which the city was known as Nicomedia. During this time, palaces and temples were built, marking a period of great significance. Over the centuries, Romans, Byzantines, Seljuks, and Ottomans ruled the city, leaving behind traces of their unique cultures and civilizations.

The name Kocaeli dates back to 1320, when the city was conquered by Akça Koca, from whom it gets its name.
