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.
The Post-war Era came to Fana with its population growth and modern sanitary equipment. This had nearly catastrophic consequences for Nordåsvatnet as a recreational area. After the runoff water got re-directed to deeper water, and later also to the fjord outside, Lake Nordås won back both its swimming guests and its sports fishermen.
Salhus has been a connecting point for sea travellers far back in time. The name probably derives from the Old Norse word sáluhús, “house for travellers”. The name may indicate that this was a place for an inn even in the Middle Ages. The place is eminently situated in the route to and from Bergen. For travellers coming by boat from Sogn and Nordhordland, Salhus is the last stop before Bergen. Travellers from the communities in Voss also came this way earlier when they were going to Bergen
Today the name “Verftet” is linked to both a district and conglomeration of buildings lying protected by Fredriksberg castle. The original shipyard was founded in the 1780s by Georg Brunchorst and Georg Vedeler. It was called Gerogenes Verft (the shipyards of the Georgs), and here ships were both built and repaired in the years after 1786.
