List of municipalities of Denmark (1970–2006)

The easternmost land in Denmark, the small Ertholmene archipelago, area 39 hectares (0.16 square miles), normally only mentioned by the name of its largest islet, Christiansø, which lies 11 miles (18 kilometers) to the northeast of Bornholm, was and is not part of a municipality or county or region but was and still is administered by the Ministry of Defence.

From 1 April 1948, Aa was changed to Å as a result of the Spelling reform (Danish Retskrivningsreformen).

From January 2011, four (4) years after the counties were abolished, the politicians in the municipality chose to return to the original spelling Aa instead of Å.

Bornholm County, which had existed since 1662, when it replaced Hammershus Len, was abolished as of Wednesday 1 January 2003, after the voters decided this in a referendum on the island on Tuesday May 29, 2001.

This merger was not a part of the structural reform that merged most of Denmark's municipalities and other entities in the public sector a few years later.
