Looking at the development of the industry and the basic concepts related to industrial heritage, this thesis is about the European Route of Industrial Heritage with the emphasis on the possibility of creating a regional route in Croatia. The European Route of Industrial Heritage is a certified cultural route of the Council of Europe and it is an example of a good practice in which industrial heritage is revitalized in a sustainable way. There are currently four Croatian sites on the route, so the question is: are there any other potential industrial attractions that could be enlisted on the route so that the regional Croatian route could be created. In order to find an answer to this question, a survey of the potential of Croatian industrial heritage was conducted in which respondents answered questions about European cultural routes, the European Route of Industrial Heritage and gave ideas for creating a regional Croatian route. After the result analysis, a potential route called Forgotten Paths of Industry was created and a possible itinerary which would preserve and revitalize the industrial heritage throughout Croatia was presented.
