Vestfold

Vestfold is a county in Norway. (It became a county again in 2024.)

It bordered Buskerud and Telemark. The county administration was in the city of Tønsberg. Vestfold was west of the Oslo Fjord. The river Numedalslågen runs through the area. Many islands are at the coast. Vestfold is mostly lowland areas. It is among the best agricultural areas of Norway.

On 1 January 2020 the county merged with Telemark to the county of Vestfold og Telemark.

Vestfold used to be a headquarters for whaling fleets. The economy of the coastal towns of Vestfold now is centered around fishing and shipbuilding. Some lumbering is done away from the coast. The district also has some of the best farmland in Norway.
