Today the name “Verftet” is linked to both a district and conglomeration of buildings lying protected by Fredriksberg castle.

Down by the fjord on the farm Berge in Tørvikbygd, is Stekkavika – a sheltered eastward facing harbour, protected against the fjord by headlands and rocks, even manifest in the name. Here is also a comprehensive milieu of coastal industry, with boathouses and sea-sheds that belong to the farms Berge, Heradstveit and Halleråker. Belonging to the farm Berge there is also a mill-house, circular saw, workshop for sloop building, and – a little further up into the woods – the old water-powered sash-saw.
