Tthe Otterstad farms lie in the innermost part of Mofjorden, on the northwest side of the river. The row of stave-built boatsheds that belong to the farm were probably constructed a little after the middle of the 1800s. Both here and on the Mo side, the boatsheds were important storage places at the seashore; wood and other farm products intended for the town; corn and merchandise in return.
Årskog farm is situated in a typical coastal landscape in a gentle terrain that slopes down from the outlying heaths down towards the fjord. The farm steading exists as it was in the 1800s. In 1980 the two brothers, Lars and Olai Årskog donated the farm with all its contents of tools and interior decoration, for museum purposes.
