The grand farm Aga on the west side of Sørfjorden, came under protection in 1937, when the agricultural reform threatened to disperse the old clustered settlement. “Lagmannsstova”, named after the “lagmann” (law speaker) Sigurd Brynjulfsson, was already protected in 1924; one of the authentic profane wooden buildings from the Middle Ages still standing. All the same it is the farmyard itself that is the key cultural monument.
Whoever wanders the mountain plateau will form time to time hit upon old mountain summer farms, with solid old stone sheds, half sunk into the ground; a building tradition that has roots into prehistoric times. When we have been satiated with untouched Nature, it is somewhat comforting to come upon the old mountain chalets - they represent a type of human encroachment that we not only accept, but appreciate. They arouse a feeling of recognition and are a distinct witness to how people in the rural communities have made use of even the most remote resources.
There are especially many seabirds inwards along the fjords of western Norway. There are not many islets, either, so if the birds want to nest, it is not always easy to find good sites. At Aksnesholmane there is an impressive colony of gulls, and the locality has been protected since 1923.
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.
On the farm of Arnatveit, high up on the slope above the highway, an old smokehouse remains standing in the courtyard of the main farm property, in the place of the old common courtyard. Today this farm lies at the outskirts of a large housing estate. Most of the farmland of the other farm properties has been sold to benefit the city’s need of sites for the new community of Arna.
Strawberry-growing on Askøy flourished in the beginning of the last century. When gardener Samson Eik took in the type "Seierherren" from Rosendal in 1909 for growing strawberries on Hop, it appeared that the soil and climate in this area was perfect for the mass production of strawberries.
