Built under the limited conditions of the 1930s, this facility symbolizes a nation’s determination to rise using its own resources; it is not only an iron production center but also one of the most fundamental building blocks used in the construction of modern Türkiye.

The foundations of this massive investment, inspired by Gazi Mustafa Kemal Atatürk’s words,

were laid on April 3, 1937. At that time, Karabük then a small, desolate village with only a few households connected to Safranbolu—was designated as the heavy industry center of the young Republic thanks to its strategic location and proximity to the Zonguldak coal basin. The first foundation stone laid by the Prime Minister of the period, İsmet İnönü, was in fact the spark that marked both the birth of a city and the beginning of a nation’s industrial revolution.

Despite the wartime atmosphere in the world and technical limitations during the construction process, Turkish workers and engineers demonstrated great determination and made the factory ready for production. On September 10, 1939, the first Turkish iron flowing from the blast furnace went down in history as the most concrete proof that Türkiye had freed itself from external dependency and become a power capable of producing its own steel.

Over time, Kardemir’s steel was used in almost every investment in Türkiye, from sugar factories to dams, from bridges to major industrial facilities. This versatile production capability and the technical support it provided for the establishment of other heavy industry enterprises earned it the rare title in world industrial history:

The Karabük Iron and Steel Works brought not only machines and furnaces to the region, but also a completely new way of life and a wave of social transformation. Worker housing, social facilities, schools, and sports clubs formed around the factory laid the foundations of one of Türkiye’s most organized and conscious industrial societies.

Karabük became a city that grew with its factory, woke up to the sound of its shift whistle, and gained its identity from it becoming one of the most vivid examples of the role of industry in social development. Providing food and employment for tens of thousands of families, this massive structure transformed the fate of an entire region by creating a sense of discipline and belonging passed down through generations.

Looking at the 89 years behind it today, we see that Kardemir continues its existence not only with the memories of the past but also with the technologies of the future. Maintaining its position as Türkiye’s and the region’s only producer of high-speed train rails, the facility also makes one of the greatest contributions to the national technology initiative by producing high-quality steel for critical sectors such as automotive and defense.

With its environmentally friendly investments, digital transformation steps, and increasing production capacity, 89-year-old Kardemir continues to enhance Türkiye’s competitiveness in the global steel market by combining its initial enthusiasm with the requirements of the modern world.
