History



Porsgrunn has been an important harbor town in the Grenland area since the late 16th century. In 1653, the Customs House was moved further down the Skien river from Skien to Porsgrunn mainly because industrial waste such as sawdust and mud made the river too shallow to allow boats to go any further up the river.[5] Moving the Custom House to Porsgrunn added to the flourishing harbor activity and Porsgrunn became a thriving market town with a ladested status.[6][7][8]
In the 18th century, Porsgrunn was the home of some of Norway's most influential families at the time, such as the Aalls, Cappelens, Løvenskiolds, and Deichmans. Also in this period, Porsgrunn was considered the cultural centre of Norway. On the ecclesiastical side, Porsgrunn was separated from the ancient rural parishes of Eidanger prestegjeld, Solum prestegjeld, and Gjerpen prestegjeld in 1764 to become a prestegjeld with its own minister. Churches within the Porsgrunn prestegjeld included Østre Porsgrunn Church and Vestre Porsgrunn Church. The city was granted limited city status as a kjøpstad in 1807, but this was expanded to full city status in 1842.[6][7][8]
The formannskapsdistrikt law of 1837 created a system of local government in Norway by establishing each town or city (ladested or kjøpstad) and each Church of Norway prestegjeld as a civil municipality. On 1 January 1838, the kjøpstad of Porsgrunn was established as Porsgrunn Municipality.[9]
During the 1960s, there were many municipal mergers across Norway due to the work of the Schei Committee.[10][11] On 1 January 1964, the following areas were merged to form an enlarged Porsgrunn Municipality:[9]
- all of Porsgrunn Municipality (population: 10,863)
- all of Brevik Municipality (population: 2,498)
- all of Eidanger Municipality (population: 13,018)
- the Bakke area of Hedrum Municipality in Vestfold county (population: 75)
- the Enigheten, Høyberg, and Skavåsen areas of Brunlanes Municipality in Vestfold county (population: 12)
Prior to the 1964 merger, the town of Porsgrunn was the same size as Porsgrunn Municipality, but after the merger, the town makes up one area within the larger Porsgrunn Municipality.
Porsgrunn was once home to Skomvær, the country's largest sailing ship. In 1985, the sculpture Amphitrite, the wave and the sea birds was unveiled in Porsgrunn. The sculpture, which is one of Jørleif Uthaug's best known works, has a nautical theme in honor of Porsgrunn's maritime history.
Government
In Norway, municipalities are the unit of local government. This means that cities and towns are simply designations for urban areas, but under current Norwegian law, they have no actual government authority. The city of Porsgrunn lies within Porsgrunn Municipality and is therefore governed by the municipal council of Porsgrunn Municipality.[12]
During its time as a self-governing town, Porsgrunn used a coat of arms that was approved for use on 16 January 1905 until the municipal merger on 1 January 1964. The new Porsgrunn Municipality adopted the same arms that the town had previously used.[13]

- Yara International (nitrogen fertilizers)
- Porsgrund Porcelænsfabrik (porcelain)
