Knudaheio inspired his major biographical work, "Knudaheio Letters" of 1904.
The furnishings are authentic, and the exterior has been unchanged since 1909, when Garborg fixed up his small house. Exhibited are photographs of Garborg, the author's furniture and other possessions, and first editions of most of his books. Arne and Hulda Garborg were buried in their garden here in 1925 and 1935.
