Grenland in the context of "Borgarting"

Upper Telemark (Norwegian: Øvre Telemark) is a traditional district in Telemark county in Norway. The area includes the inland areas of Telemark. More than two-thirds of the total area of Telemark—more than 10,000 square kilometres (3,900 sq mi)—belong to the traditional region of Upper Telemark. Conversely, the area of "Lower" Telemark refers to the more densely populated, flatter coastal area of Grenland and traditionally also includes Central Telemark. Upper Telemark has a varied and often scenic landscape, with many hills, mountains, valleys and lakes.

Upper Telemark was originally known simply as Telemark and is named for the Thelir (Old Norse: Þilir), the ancient North Germanic tribe that inhabited what is now called Upper Telemark and Numedal in the Migration Period and the Viking Age. Upper Telemark is known for its folk traditions within music, clothing, handcrafts, food and architecture. The region is also distinctly marked by its dialect of Norwegian.

Vestfold (pronounced [ˈvɛ̂stfɔɫ] ) is a county and a current electoral district in Norway. Located on the western shore of the Oslofjord, it borders Buskerud and Telemark counties.

Vestfold is located west of the Oslofjord, as the name indicates. It includes many smaller, but well-known towns in Norway, such as Holmestrand, Horten, Åsgårdstrand, Tønsberg, Sandefjord, Larvik and Stavern; these towns run from Oslo in an almost constant belt of urban areas along the coast, ending in Grenland in neighbouring county Telemark. The river Numedalslågen runs through the county. Many islands are located at the coast. Vestfold is mostly dominated by lowland and is among the best agricultural areas of Norway. Winters last about three months, while pleasant summer temperatures last from May to September, with a July average high of 17 °C (63 °F).

Midt-Telemark is a traditional district of Norway situated in Telemark county. It is made up of two municipalities: Midt-Telemark and Nome. The largest population centres in the region are Bø, Ulefoss, Bjervamoen, and Gvarv, of which Bø is the largest with 3,609 inhabitants. The district is located between Øvre Telemark (upper Telemark) and Nedre Telemark (lower Telemark).

Historically, the areas of Midt-Telemark included the old parishes of Bø and Sauherad. Both parishes became municipalities on 1 January 1838 when the formannskapsdistrikt law came into effect. Lunde Municipality was split off from Bø in 1867. In 1964, Lunde was merged with the neighboring Holla Municipality to form the new Nome Municipality. Holla was never historically part of Midt-Telemark, instead it was often included in the Grenland district.

Bø is a former municipality in Telemark county, Norway. It was part of the traditional region of Midt-Telemark, but was historically regarded as part of Grenland. The 263-square-kilometre (102 sq mi) municipality existed from 1838 until its dissolution in 2020. The area is now part of Midt-Telemark Municipality. The administrative centre was the village of Bø i Telemark. Other villages in the municipality included Folkestad and Nordbøåsane.

Prior to its dissolution in 2020, the 263-square-kilometre (102 sq mi) municipality was the 291st largest by area out of the 422 municipalities in Norway. Bø was the 161st most populous municipality in Norway with a population of 6,630. The municipality's population density was 25 inhabitants per square kilometre (65/sq mi) and its population had increased by 20.2% over the previous 10-year period.

Bamble is the 87th most populous municipality in Norway with a population of 14,172. The municipality's population density is 50.2 inhabitants per square kilometre (130/sq mi) and its population has increased by 0.3% over the previous 10-year period.

Frier or Frierfjord is a fjord in Telemark county, Norway. The 14-kilometre (8.7 mi) long fjord is located along the Skaggerak coast in the traditional district of Grenland and it forms the border with the municipalities of Bamble, Skien, and Porsgrunn. The fjord is actually an inner arm of the Langesundsfjord, and historically (well into the 1700s) this fjord was also known as the Langesundsfjord. The fjord stretches from the opening to Langesundsfjord in the south to the mouth of the Porsgrunn River in the north. The much smaller fjord of Gunneklevfjord opens into the Porsgrunn/Skien River and is separated from Frierfjorden by the peninsula of Herøya.

The Frierfjorden narrows to a width of about 300 metres (980 ft) at Breviksstrømmen, the mouth of the fjord, where the town of Brevik sits on the northern side and the town of Stathelle lies on the southern side. The Brevik Bridge crosses Breviksstrømmen between the two towns. A little further into the fjord the newer Grenland Bridge crosses the fjord, carrying the European route E18 highway across Norway's highest cable stayed bridge.
