Chateau buildings (castles) are an integral part of urban and rural settlements and represent an important historical, urban and social element of our cultural landscape. It is a sad fact that many of these buildings are now abandoned and dilapidated. This problem is mostly accentuated in the Central European region, where it is directly linked to the political and property changes in the first half of the 20th century, which forced an interruption of their original utility purpose and natural functionality. The intention of this paper and its aim is to define the chateau brownfield and to form its basic theoretical concept in the context of a synthesis of multidisciplinary concepts. This is a sub-area of brownfields that has not yet been independently researched and professionally elaborated. However, there is no doubt that chateau brownfields represent a significant development potential of the regions and the economy. The results of this paper (determination of chateau brownfields) is thus a necessary initial step to solving this topic on a theoretical and practical level.
