„20357“, a walkable 100t concrete sculpture, commissioned by the City of Hamburg. Zahlmanns idea was, to use the post code of the area and create a monumental sculpture. Residents and visitors of the Karolinenviertel can use it multifunctional.
Art in public places had been often an annexion of a location, which favored the qualified public and the municipality preferred to use it as a method to upgrade an area.
Heiko Zahlmann ́s work „20357“ is not only a specific local sculpture for residents and visitors of the Karolinen quarter; it is also walkable and has a valuable use.
This aspect of „20357“ draws an interest for parts of the public, like skateboard riders, whose appearance in public has been regarded as an increasing problem in urban spaces against the intentions of architects and city developers.
Zahlmann, as a former graffiti artist, originated as well in a subculture, made a conscious decision for plural use of possibilities about his sculpture and he truly equipped the Karolinen Plaza with a truthful public character.
Certainly this choice will create conflicts of interest between different user groups, but in the end the discussions will show how heterogeneous the Karolinen quarter still is.
