Харальд III
Grimdalen is especially known for her many animal sculptures, made in a simplistic style, often in granite, such as "Gaupe" (Lynx, 1928), "Bjørn" (Bear, 1933). She made several contributions to the decoration of Oslo City Hall, after surprisingly winning the decoration contest in 1938, such as "Tømmerfløtere" (Log drivers) and "Dyrefontene" (Animal fountain), and the large equestrian statue of Harald III on the west wall (1938–1950). A relief of psalmist Magnus Brostrup Landstad (1951) is placed outside the church of Seljord.
