Sport has become a significant part of our lives in the modern era and sporting sites contribute considerably to the image and texture of modern cities. Regarding the popularity of sport, especially football, the stadium has become an important modern space where specific kinds of social interaction take place. Despite the fact modern stadiums had their pre-modern models, they have been transformed substantially, so that we can talk of new urban spaces. This paper shows how football pitches gradually turned into stadiums, using the example of the Czech lands. The choice is by no means autotelic: interwar Czechoslovakia had one of the most successful football teams on the continent.
