Did you know that the area of Međimurje, namely village Peklenica, was the first oilfield found in Croatia? The locals claim that the first oil exploration concession in the world was issued in 1858 in Peklenica, which means Peklenica would've been the birthplace of the oil industry. The oil exploration had far-reaching consequences that affected today's tourist offer. During the search for new oil foundations, excavation has found a source of underground thermal water. Thanks to this "random" discovery of thermal waters, Međimurje has become a true wellness destination.
