Countship of Larvik

Laurvig was intended to be the leading countship in Denmark-Norway: "hvilket Grevskab skal for vores Rigers første Grevskab herefter holdes og agtes skal.".

The building was started in 1674 and completed in time for Gyldenløve's third wedding, with Antoinette Augusta von Aldenburg, on August 16, 1677.

The coat of arms is blazoned as follows: "I blåt en oprejst, kronet hvidspættet løve med hovedet set for fra ("leopard") i en krum gul hellebard.

By patent of 11 February 1692, succession was changed, so that only Gyldenløve's sons and their male descendants could inherit.
