Gulskogen Gård is part of Drammen Museum. The manor house lies on the banks of the Drammen River. It has been preserved, largely intact, as it would have been in the nineteenth century. The manor was once owned by the wealthiest merchant in Drammen, Peter Nicolai Arbo, who bought the property in 1794. The interior of the building contains fine furniture, furnishings, paintings and ornaments. The garden is landscaped in the English style.
