In the late 13th century, the first water powered mills were introduced in Norway. At Sevheim, Finnøy, an old mill has been restored and is a good place to get knowledge of how grain was milled i earlier times. The millstone in the house is probably from Talgje, one of Finnøy's neighbouring island, and has been dated to 1849. The house originally had a turf roof and no wall cladding for the first years. The Sevheim mill belonged to Sevheim farm, in earlier times every farm had its own mill. In the Sevheim stream only, 11 mills were located. The restoration of the mill was finished in 1998.
