# Tønsberg Municipality

Tønsberg (pronounced ) is a municipality in Vestfold county, Norway. It is located in the traditional district of Jarlsberg. The administrative centre of the municipality is the city of Tønsberg which was established in the 9th century. Other larger population centres in the municipality include Barkåker, Bergsåsen, Brekkeåsen, Eik, Fon, Gretteåsen, Husøy, Husvik, Linnestad, Ramnes, Rånerudåsen, Revetal, Sem, Svinevoll, Teie, and Vear.
The 329-square-kilometre (127 sq mi) municipality is the 254th largest by area out of the 356 municipalities in Norway. Tønsberg is the 17th most populous municipality in Norway with a population of 58,561. The municipality's population density is 179.6 inhabitants per square kilometre (465/sq mi) and its population has increased by 16.6% over the previous 10-year period.
Tønsberg Municipality is home to Tønsberg Fortress on Castle Mountain, which includes ruins from Castrum Tunsbergis, Norway's largest castle in the 13th century. Tønsberg is also home of Oseberg Mound, where the 9th-century Oseberg Ship was excavated. The large city of Tønsberg was founded in the 9th century, one of the oldest cities in Norway, and it is also the 9th largest city in Norway.

## General information

The town of Tønsberg was established as a municipality on 1 January 1838 (see formannskapsdistrikt law). On 1 January 1877, the growing town of Tønsberg was enlarged by taking an area from Sem Municipality (population: 61) and another area from Nøtterøy Municipality (population: 102). On 1 January 1980, an unpopulated area of Nøtterøy Municipality was transferred to the town of Tønsberg. On 1 January 1988, the town of Tønsberg (population: 8,896) was merged with Sem Municipality (population: 21,948) to form a new, much larger Tønsberg Municipality.
On 1 January 2017, the village of Vear was transferred from Stokke Municipality to the neighboring Tønsberg Municipality. On 1 January 2020, Tønsberg Municipality merged with the neighboring Re Municipality to form a much larger municipality.

### Name

The municipality is named after the old town of Tønsberg (Old Norse: Túnsberg) since the first Tønsberg Church was built there centuries ago. The first element is the genitive case of tún (n) which means "fenced area", "garden", or "field around a dwelling". The last element is berg (n) which means "mountain" or "rock". The name originally referred to the fortifications on Slottsfjellet. The old spelling of the name has been retained in the name of the local diocese, Tunsberg bispedømme.

### Coat of arms

For a long time, the city and municipality did not have a formal coat of arms, but instead an old medieval seal dating back to 1349 was used in its place. The blue and white circular seal shows the Tønsberg Fortress surrounded by a ring wall on a mountain with the sea in front. There is also a longship in the water in front of the fortress. Around the seal are the Latin words SIGILLVM BVRGENSIVM D'TVNESBER which means "This is the seal of Tunsberg".
In preparation for the merger of Re and Tønsberg Municipalities, a new coat of arms was adopted in 2018 for use starting on 1 January 2020. The blazon is "Per pale argent a longship stem azure and azure a seedling argent". This means the arms are divided with a vertical line. The field (background) to the right of the line has a tincture of azure. To the right of the line, the field has a tincture of argent which means it is commonly colored white, but if it is made out of metal, then silver is used. There are two charges on the arms. The charge on the left side is a longship stem, symbolizing the one on the Oseberg Ship and the great Viking Age history in the area. This stem has a tincture of azure. The charge on the right side is a seedling, symbolizing local agriculture. This seedling or sprout has a tincture of argent which means it is commonly colored white, but if it is made out of metal, then silver is used.

### Churches

The Church of Norway has nine parishes (sokn) within the municipality of Tønsberg. It is part of the Tønsberg domprosti (arch-deanery) in the Diocese of Tunsberg.

## History

The city of Tønsberg has existed for centuries. On 1 January 1838, the formannskapsdistrikt law went into effect, making all cities and rural parishes across Norway into civil municipalities with self-governing councils. The city of Tønsberg was surrounded by Sem Municipality for many years until 1988 when Sem Municipality and the city of Tønsberg were merged, creating a new Tønsberg Municipality with a much larger size and population than the city was before the merger. The city continued on as the administrative centre of the new municipality. In 2017, the village of Vear was transferred into Tønsberg Municipality from Stokke Municipality. In 2020, the neighboring Re Municipality was merged with Tønsberg Municipality, more than doubling its size again. The new Tønsberg Municipality included much more rural area than urban area, with most of the urban settlements in and around the city of Tønsberg in the far southern part of the newly merged municipality.

## Economy

Since the municipality was enlarged, Tønsberg is now the largest agricultural municipality, with an agricultural area of about 117,000 decares (117 km$^2$; 45 sq mi) (2018). Cereal cultivation dominates, but vegetable production is significant. Tønsberg is the municipality in Vestfold that has the highest number of cattle (both dairy and meat cows). In forestry, 43,000 cubic metres (1,500,000 cu ft) of trees were harvested in 2018, about 80% of which was spruce.
The city of Tønsberg has long traditions in shipping, industry, and trade. Today, the municipal business-base is predominantly small and medium-sized companies. The most important industries are the food industry, including a large slaughterhouse (Nortura) and a large dairy (Tine), as well as a flatbread factory. The workshop industry is also significant, particularly the metal goods industry. Esso's refinery at Slagentangen was closed in 2021. There is also a large silverware factory and the country's only bell foundry at Nauen in Sem (Olsen Nauen Bell Foundry). The most important industrial areas are located along the Canal and the adjacent areas of Byfjorden, both on the mainland and the Nøtterøy side. Important industrial areas are also found along the Oslofjord from Husøy and northwards to Vallø and Slagentangen. There is also a lot of summer tourism along the coast.

## Geography

Tønsberg is a municipality in Vestfold County, on the western shore of the Oslofjord. Tønsberg lies north of Færder Municipality, west and south of Horten Municipality, and east of Sandefjord Municipality. Most of the municipality lies on the mainland plus a small area on the north end of the island of Nøtterøy. Just south of Tønsberg are the islands of Nøtterøy and Tjøme, which are tourist destinations.
The bedrock in the municipality consists entirely of igneous rocks. The landscape is characterized by slightly hilly, elongated and wooded hills with crevasse valleys running north-south and with heights in the western part of the municipality reaching as high as the 400-metre (1,300 ft) tall Snippane, just west of Vivestad. Streams and rivers follow the north-south running valleys. The Storelva river, which flows centrally through the municipality from north to south, and the Merkedamselva river in the west unite and become the river Aulielva which then flows into the Tønsbergfjorden.
