Towards a more sustainable and responsible tourism

The slag heaps are becoming more and more attractive as nature reclaims the land. However, these slag heaps were not built to receive visitors and unrestricted numbers could have a significant impact on this heritage. Through this cross-border project, we wish to pursue the development of tourism and therefore the economy of the area, while preserving the integrity and heritage value of the sites.
