Upper Silesia belongs to one of the most industrialized regions in Poland. In the last decade the industry has undergone significant changes in terms of the ownership structure, the number of employed individuals, as well as production profiles. Consequently, liquidation and restructuring processes are being implemented. The mentioned changes, which are taking place on a large scale, have contributed to the degradation of the region. As a result, the following questions need to be addressed: altering real property use, redeveloping post industrial land, protecting and sustaining those areas and buildings, which may qualify as cultural heritage. This paper concerns restructurization, rehabilitation, revitalisation and recultivation of post industrial land (brownfield sites). The directions of changes in Upper Silesia's post industrial land have been examined in the context of the regions characteristics. The results of the conducted analyses indicate a shift from heavy industry use to retail, office, residential, trade-expo, tourist, recreation uses as well as modern industrial use. Based on the conducted case studies an attempt has been made to identify the influence the above mentioned changes have had on the local real estate markets.
