Most of the coats of arms of current boroughs [2] have changed some elements in their field: Some of them have created a "fusion" of themes of the merged Bezirke (Charlottenburg-Wilmersdorf, Lichtenberg, Steglitz-Zehlendorf, Tempelhof-Schöneberg); others have modified their themes taken from one of the two (or more) former merged boroughs (Friedrichshain-Kreuzberg, Marzahn-Hellersdorf, Mitte and Treptow-Köpenick). Only the unchanged boroughs of Neukölln, Reinickendorf and Spandau haven't changed their field. The coat of arms of Pankow was created with a new design in 2008, having been the only district without an emblem for 7 years.
