An interesting exhibition about the origin of the oil shale, the history of its extraction and its modern use. All this fits in one large hall, many stands of which have remained since Soviet times and are cute handwritten inscriptions. The second hall is hung with paintings showing the work of miners and other workers in the oil shale industry. It might seem naive, but still nice. Do not miss to talk to the caretakers they are happy to tell about the past and present of Kohtla-JArve.
