The parish of Holt was established as a civil municipality on 1 January 1838 (see formannskapsdistrikt law). According to the 1835 census, the municipality had a population of 3,116.[4]
On 1 January 1881, a part of Holt with 52 inhabitants was moved to the neighboring municipality of Dypvåg, and on 1 July 1919 another part of Holt with 14 inhabitants was moved to the neighboring municipality of Moland. During the 1960s, there were many municipal mergers across Norway due to the work of the Schei Committee. On 1 January 1960, the municipalities of Holt (population: 3,759) and Dypvåg (population: 1,805) plus the town of Tvedestrand (population: 868) were merged to form an enlarged municipality of Tvedestrand.[5]
Name
The municipality (originally the parish) is named after the old Holt farm (Old Norse: Holt) since the first Holt Church was built there. The name is identical to the word holt which means "small forested area" or "grove (of trees)".[6]
The municipal council(Herredsstyre) of Holt was made up of 21 representatives that were elected to four year terms. The tables below show the historical composition of the council by political party.
Holt Church (Holt Kirke) is a cruciform church dating from the 1100s. The medieval-era church was constructed of stone. In 1753, it was expanded. The extension, choir and transepts were built of wood. The rebuilt church was also equipped with a chancel arch, decorated in the rococo style. The church has a baptismal font made out of soapstone, carved in high Gothic style. The Baroque altarpiece from 1732 is carved with a painting of Jesus in Gethsemane.[13]
