It´s some time ago I posted some images from Alvøen Hovedgård but I never actually managed to finish it. Here is a link to the museum I believe: Alvøen Hovedgård, this place is wonderful and great to visit if you are in Bergen. The industry part started already in 1626 and Alvøen Hovedgård/Gamle Mølle is one of the best kept industry buildings in Bergen. They started with grainmill(møllen).
