Throughout history, Kocaeli has been a gateway connecting Europe with the Middle East and Asia.It was the capital of the ancient kingdom of Bithynia and a crucial trade centre for the Eastern Roman Empire.

Today, along the commercially active Black Sea and the Marmara Sea shorelines, Kocaeli boasts 34 ports and industrial facility docks, making it a logistics heaven and a gateway to global markets.

Alongside its industry, the province is also striving to develop its sea and lake tourism, and to some extent, its winter sports, providing alternatives for water sports along the beaches of the Black Sea and a ski resort on the hills of Kartepe. Horse breeding is also a growing trend in the province. The nation’s best race horses are bred at stud farms located here in Kocaeli.
