Zonguldak
Zonguldak is a city and the capital of Zonguldak Province in the Black Sea region of Turkey. It was established in 1849 as a port town for the nearby coal mines in Ereğli and the coal trade remains its main economic activity.According to the 2009 census, Zonguldak has a population of 108,792.
The city’s development and rapid rise in population were associated with the growth of this coal industry after the mid-19th century. Mining was extensively developed by the government after 1940, and much of the city’s workforce has remained engaged in work related to coal. The Zonguldak Technical School of Mining is in the city. There are also chemical plants and coke ovens. Zonguldak is connected by rail with Ankara and by sea with Istanbul.
Zonguldak province is well forested and mountainous. It is drained by the Araç, Devrek, Filyos, and Ova rivers, along which are small but fertile lowlands producing corn (maize), flax, and vegetables. It is the centre of Turkish heavy industry, containing the country’s largest iron and steel complexes at Karabuk and Eregli and the largest coalfields near Zonguldak city.
