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, Logstor, Støvring and Nibe. In northeastern Himmerland is the Lille Vildmose, Denmark's largest high bog, which has a rich population of wild birds.It is generally assumed that the name is derived from the tribe of the Cimbri since, in the Geography of Ptolemy (2nd cent. AD), the Kimbroi are located in the northernmost part of the peninsula of Jutland, called Kimbrikē chersonēsos.
