Bjerkebæk was the home of Sigrid Undset from 1919 until she fled Norway after the German invasion in 1940. Undset, who won the Nobel Prize for Literature in 1928, lived and wrote here during the most productive years of her career, completing Kristin Lavransdatter and Olav Audunssøn in the house and garden. The property has been preserved as a museum and gives a vivid sense of the life of an early 20th-century Norwegian intellectual.
The house is furnished as it was during Undset's time, with her personal belongings, furniture, and books. The garden, which she designed and planted herself, has been restored. The museum organises the Norwegian Festival of Literature, which takes place in Lillehammer each spring and draws writers from across Scandinavia and internationally. The house is a short walk from the upper end of Storgata.
