[1] The estate is now owned by The State of Norway and is an official national monument, as well as a museum.

Carsten Anker went bankrupt in 1822 and the ownership of the estate was transferred to various British creditors in 1823.

A group of private citizens led by Henrik Wergeland organized a fundraiser that allowed them to buy the building with the pavilion and surrounding garden (Eidsvollsparken).

The manor has been renovated since Carsten Anker and his family lived there and now has become a museum.
