Research was performed on three former iron and steel works areas located in the Ruhr region in Germany: one of the Thyssen's ironworks in Duisburg – Meiderich, the area of steelworks complex Gute-Hoffnungs-Hütte in Oberhausen and the area of the iron and steel works Phönix in Dortmund - Hörde. Methods were applied specific to urban morphology. For each object of study a comparative analysis of the town plan was carried out. Town plans were compared before and after the revitalization process and special attention was paid to land use. This allowed us to observe morphological and functional changes which occurred as a result of the revitalization of the study areas. The research showed that the revitalization of post-industrial space may be conducted in many different directions but irrespective of that it has a huge impact on the evolution of urban space in both a morphological and a functional way. The extent to which revitalization affects morphological and functional structure of urban space depends on the future plan for the spatial development of the site and its attitude to its post-industrial heritage.

Introduction technical and industrial infrastructure and 4) urban wastelands (LORENS, 2010). Revitalization is a sequence of planned actions A special type of degraded urban spaces are aimed at social and economic recovery of the brownfield sites. According to LORENS’S (2010) degraded part of the town. It includes comprehensive division brownfield sites are included in the third changes in spatial, functional, urban, infrastructural, group – the areas with technical and industrial social and environmental structure of the urban infrastructure. Characteristic features of this group space. It is a particularly complex, long-lasting are: the loss of hitherto function and the exclusion and interdisciplinary process, in which numerous from use, and also the lack of permanent inhabitants. organizations and institutions are actively involved The success of the revitalization of such areas is (KACZMAREK, 2001; HELLER, 2002; STAWASZ & SIKORA, dependent on external factors, in particular the 2007; LORENS, 2010; KOPEĆ, 2010). The notion of spatial accessibility, and internal factors such as ‘revitalization’ refers to actions conducted on the size of the area and the type of buildings (GASIDŁO, existing urban areas which, for various reasons, 1998; DOMAŃSKI, 2000). The advantages of have been degraded (BEHR ET AL., 2003). Considering brownfield sites are their proximity to the city the initial use of the urban space, degraded urban centre and the transport infrastructure (BEHR ET areas can be divided into four groups: 1) housing AL., 2003). However, the environmental pollution, areas, 2) multifunctional complexes, 3) areas with infrastructural barriers and ownership barriers 31 may make it difficult to re-use former industrial domestic fuel, but in the 18th century many forges areas (JARCZEWSKI, 2010). changed their energy sources. They switched Because of the specific circumstances outlined from wood to coal which increased the demand above, the revitalization of brownfield sites is for this raw material. The first steel on the basis particularly complicated. It is often associated of coal was produced in the Ruhr area in 1826. with regeneration (restoring value through Hence, an industrial landscape developed in the renovation or modernization) of historical buildings Ruhr area which consisted of coking plants, or technological monuments, it frequently requires steelworks, ironworks, employee housing districts expensive liquidation of industrial installations and factories. The consumption of land increased and purification of the environment from and simultaneously a rapid growth of the pollution (land reclamation), but mainly it is population occurred proportionally to the increase related to the introduction of new functions and in production of coal and steel. This situation communities into these areas (DOMAŃSKI, 2010; lasted even after the World War II (HOPPE ET AL., LORENS, 2010). 2010; REGIONALVERBAND RUHR, 2006). This paper shows the relationship between In 1960. in the Ruhr region there was a crisis revitalization and evolution of the urban space, of coal surplus, which was followed by a crisis in which is within the range of research interests of the steel industries in 1970. Coal mining and steel urban morphology. Evolution of the urban space production were no longer commercially viable is reflected in morphological and functional changes. and many mines and foundries had to be closed Morphological changes refer to the transformation of down (FAUST, 1999; FARRENKOPF, 2009). It was physical elements of the town (which are buildings the beginning of the revitalization of this region. and their related open spaces, plots or lots, and The new strategy for the economic re-orientation streets) and changes in its layout (KOTER, 1994). of the Ruhr area was to change it into a region In turn, functional changes are understood as specializing in the service sector. The big step to succession of function or relocation of function solve the problems caused by the restructuring of (SŁODCZYK, 2003). It should be noted that in industry like the unemployment or re-use of post- morphological studies the notion of function industrial space was the International Building usually refers to the land and building utilization Exhibition (IBA) Emscher Park 1989-1999.

So the aim of this paper is to consider how and for the cultural consciousness in the Ruhr different may be the impact of revitalization on area (PARENT, 2005; WILLMS, 2005; WEHLING, 2006). the evolution of similar urban areas, especially As a result the Ruhr region, called recently “the brownfield sites.
