Historic farm in a scenic area with walking paths open the public. Bygdø Royal Manor is a fully operational organic farm, and you are free to visit the grounds and animals on Saturdays in spring and autumn. The farm has 60 dairy cows, 90 calves, 30 sheep and nine ponies, and almost half of the farm's 494 acres are used to produce feed for the livestock. Horseback riding lessons for children are offered in the autumn and spring. The Manor has been linked with the Norwegian Royal family since 1305, when King Haakon V Magnusson gave Bygdøy as a gift to his queen Eufemia. The main building was built in 1733 by Count Christian Rantzau, and is presently a summer residence used by H.M. King Harald V. Bygdøy Royal Manor is part of the Norwegian Folk Museum.
