It is natural for people to preserve the most important tangible and intangible traces of their lives in various ways. Industrial heritage is a topic of public interest. One of the reasons is that there is still fear in human consciousness of the negative roles of industrial heritage such as something noisy. ugly, environmentally unacceptable, which seems insufficient for the development of space and architecture. However, in the 21st century, during the reconstruction of the economy and the connection of people's environmental awareness, the industrial heritage is gaining in value. The aim of this research is to investigate the industrial heritage of Croatia that has been used for the purpose of industrial tourism development. Industrial history of Croatia today, together with the World's, shares the same fate of the neglected examples of modern industrial architecture. Due to lack of funds on all state levels it's extremely important to think how to develop cultural content in the locations of industrial heritage that will be self-sustaining. Although it is important to take the desires of tourists into account, the embedment into urban and sociological environment is essential. Brownfield investments play a key role in investing in existing facilities and giving them a new role - turning them into industrial heritage. It is very difficult today to find authentic buildings of a certain time. However, research by scientists has shown us that there are still a small number of authentic buildings that have been abandoned because the then owners did not follow new market trends - new technologies, and thus fell out of market competition. Just such monuments became a key element for researching the architecture of that time. Therefore, it is necessary to turn such spaces into the cultural heritage of the area in order to clearly show us, but also future generations the development of building principles and the introduction of materials that open the way to modern and contemporary ideas.
