In the paper it has been shown the possibilities of post-mining areas development in the two Polish mid-sized cities – Sosnowiec and Zielona Gora. The area in Sosnowiec includes part of the former “Niwka” coal mine while in Zielona Gora – former “Krośnieńska” brickyard and lignite mines operating within the Consolidierte Grünberger Gruben company. Today, the both areas are wasteland, with a strong degradation of the soil surface. Authors of this paper have proposed for the described areas the new development as a park with elements from their industrial past. Thus, in addition to recreation and leisure, the areas will have the interesting, unique features of thematic parks referring to history of the cities.
