Oil shale in Estonia

Kohtla-Järve () is a city and municipality in Ida-Viru County, northeastern Estonia, founded in 1924 and incorporated as a town in 1946. The city is unusual among Estonian municipalities due to its discontiguous territorial span, being made of several separated parts, with the two largest of Kohtla-Järve proper (referred to as Järve) and Ahtme, both of which have populations of around 20,000 residents, being located about apart, with the now separated town of Jõhvi located between them. Several other settlements in north-eastern Ida-Viru county are administratively districts of Kohtla-Järve. K
