Jarlsberg

Vestfold county, in which former Jarlsberg in blue.

Jarlsberg was a former countship that forms a part of today's Vestfold county in Norway.

The former countships of Jarlsberg and Larvik were merged into a county in 1821. Jarlsberg and Larvik's County (Jarlsberg og Larviks amt) were renamed Vestfold in 1919.[1]

Created in 1673 as Griffenfeldt Countship (Griffenfeld grevskap), it was after a few years known as Tønsberg Countship (Tønsberg grevskap) until 1684, when the name became Jarlsberg. Dating to 1681, the countship was associated with members of the Dano-Norwegian noble family, Wedel-Jarlsberg.[2] The countship was abolished in 1893 in accordance with Norway's nobility law, but the manor is still in its own family.
