The most interesting phenomenon of the two last decades of 20th century was renovation and collectorization of historical centre of Prague. The case study from the area of the Celetná Street (Old Town) shows possibilities of interpretation of archaeological situations, recognized during shallow collector tunnels mining.
A collection of earthenware vessels of the Bell Beaker Culture shows not only the oldest traces of anthropogenic activities in the area, but also the development of sub-features of the quaternary Vltava river valley before genesis of local medieval urbanism.
