In the southwest of the Istrian peninsula is the small town of Raša, next to the river of the same name. The development of the town is closely related to the exploitation of coal, which began in the 17th century, and it was precisely on the basis of this energy source that the town's expansion and massive construction took place. In accordance with the rapid development, other branches of the industry are also beginning to develop, including the production of machine tools, which forms the basis of the later separated Prvomajska Raša plant. This is followed by a major expansion of the machine factory and an innovative approach, which allows the products to be marketed on all continents. The large number of workers and the quality of the products put Prvomajska on the world map of manufacturers of advanced machine tools, which, at the time they were created, were extremely advanced for the previous approach to the design and performance of machines in the industry. Due to the large amount of sulfur in the coal, exploitation in the area of Raša and beyond is rapidly being abandoned, and coal mines are closing and collaterally developed industry is dying. Today, the industrial facilities are abandoned and dilapidated, and conversion is still not an immediate investment option, both because of property and legal relations and because of uninterested investors. The future is not in sight for huge abandoned complexes, but every new day brings new hope for the future, and the redevelopment and flourishing of the creative branch, be it industry or some other activity. Many ingenious environments take advantage of the potential of European funds, and turn dilapidated buildings into a place where human presence has reappeared, whether as a visitor, as a worker, or as a child's smile. What remains today represents the industrial architectural heritage, which has only been valorized, registered and protected in the last fifty years. And this complex will shine again in the future. It is up to the self-government and the state to lay the foundation for a turnaround in the use of this space and the basis for the revitalization of that industrial complex.
