What is "himmerland"

Himmerland is a peninsula in northeastern Jutland, Denmark. It is delimited to the north and the west by the Limfjord, to the east by the Kattegat, and to the south by the Mariager Fjord. The largest city is Aalborg; smaller towns include Hobro, Aars, Løgstør, Støvring and Nibe. In northeastern Himmerland is the Lille Vildmose, Denmark's largest high bog, which sustains a rich bird life of international importance.
