Alvøen is one of the oldest industrial places in Norway. As early as the 1620s a gunpowder mill was built here. The place itself was well situated for industrial activity, lying only 100 m from the waterfall, which provided power for the mill, and a good harbour wherefrom the products were shipped. The success of the gun-powder mill varied in the 1600s and 1700s, but what made Alvøen best known was its paper production.
Valestrand became a centre for the tanning industry in Osterøy; one of the old crafts that has developed into a local industry with many places of work. From the 1870s ever more ventures were started. Many of the large sea houses we see today around the bay have been places for tanning and leather enterprises.
The first finds of pyrite at Litlabø in Stord came to light in 1864. Forty years later sulphuric ore was mined from an open mine. From 1874 to 1880 it was used for dynamite production. That came to a sudden end when the factory exploded and three people died.
From his loft window on the doctor’s farm at Tangarås the young Hans Ernst Kinck had a view of the fjord and the Mauranger mountains. The fjord settlements in West Norway made a strong impression on the young boy when his family moved from Setesdal, from “the stifling mystique of the ballad”, to Strandebarm in 1876. The new district doctor bought the old captain’s farm at Tangarås, which had for some time been a military head farm after Håbrekke further into the settlement.
