Already in the Middle Ages the good harbour at Leirvik provided a connecting point. Here was a court of law, and a guesthouse was established here in the 1600s. But Leirvik never achieved the status of a trading post or a ship-loading place. In the census of 1865 parts of the farms Nordre Bjelland, Leirvik and Orninggård are mentioned as the “Coastal district of Lervig”. And the community grew around the old guesthouse location early in the 1800s.
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.
