The article describes the phenomenon of urban space in Lodz being transformed by graffiti and wall-writings. The graffiti samples selected for analysis may be described as conveying a message that is easily understood by every local. This seemingly meaningless composition of wall-writings is highly influential in fact and transforms the surrounding city space. The author, by analysing the content of the graffiti, its graphical form and space context in which it appears, explores the way in which graffiti transforms urban space in the city of Lodz. The subject of the research is photographic documentation made in 2006 and 2008 in the city centre and some of the residential areas situated on the outskirts of the city.
