As the land area can be observed directly from any other plot, the figure is not included. By visual observation it seems that the largest polygons are located on the city outskirts rather than in the city center. This corresponds with the urban design as the city center contains mostly historical apartment blocks whereas on the outskirts large concrete panel housing estates, especially on the eastern (Černý Most) and southern (Jižní Město) tips were build in the past 60 years 1.
