General information The parish of Christianssund was established as a municipality on 1 January 1838 (see formannskapsdistrikt law). Initially, the small island municipality included just the town of Christianssund and its immediate surrounding area. During the 1960s, there were many municipal mergers across Norway due to the work of the Schei Committee. On 1 January 1964, Kristiansund Municipality was merged with the tiny Grip Municipality (population: 104) to the northwest and the Dale area of Bremsnes Municipality on Nordlandet island (population: 963). The neighboring Frei Municipality was merged with Kristiansund on 1 January 2008 creating a much larger Kristiansund Municipality. Toponymy The municipality is named after the town of Kristiansund. Historically, it was spelled Christianssund. The name comes from the Danish-Norwegian King Christian VI who founded the town in 1742. The last element of the name, sund, means "strait". The old name of the town/village (originally the island Kirkelandet) was Fosna or Fosen () which means "hiding place" (here 'hidden port'). It was also often named Lille Fosen ("the small Fosen") to distinguish it from the island Storfosna ("the big Fosen") in Ørland. Before 1877, the name was spelled Christianssund, from 1877 to 1888 it was spelled Kristianssund, and since 1889 it has had its present spelling, Kristiansund. Before the introduction of postal codes in Norway in 1968, it was easy to confuse the name Kristiansund with Kristiansand in the south. It was therefore obligatory to always add an N (for north) to Kristiansund (Kristiansund N) and an S (for south) to Kristiansand (Kristiansand S). This is pretty much still practiced and also occurs in some other contexts than postal addresses. Coat of arms The coat of arms was granted on 27 June 1742. The arms were
