In the article the specifics of the tourism product in projects related to the adaptation and using of post-mining objects and sites were presented. The article presents an assessment of the possibility of building a branded tourist product based on the relics of the mining industry in the context of the development and implementation of subsequent phases of the project consisting in making these relics available to tourists.
