Civic heraldry of Germany - Deutsche Wappen (Gemeindewappen/Kreiswappen)
The arms were granted on February 2, 1966.
The upper half shows a golden lion on a green field. This was the symbol chosen by the 8 villages that received many privileges in the 17th century. Kolshorn was one of these villages.
The lower half shows two deer antlers as a symbol for the forests and the rich wildlife in the area. The so-called wolf's iron is taken from the arms of the (former) district Burgdorf.
