In 1868 the first stone workers came to Rubbestadneset to take out the granite for the Skoltegrunns Pier, predecessor of the Skoltegrunns wharf in Bergen. Later granite was also taken out from the area, around Innværs Fjord and UransvågenN. The activity probably peaked around 1900, with over 40 men at work. 15 years later, it was finished.
"And here these endless kingdoms and these toils for a rich working life far and wide have lain and slept for a hundred thousand years! Right up until the Voss Railway came in 1883 and woke them, like the prince in the fairytale who awakened the Sleeping Beauty."
In Ålvik quartz has long been used to produce ferro-silicon. The quartz was collected from the other side of the fjord, from the mountainside above Kvalvikane.
Ullensvang church, situated beside the vicarage, in idyllic surroundings on the headland just inside Lofthus municipality, is mentioned for the first time in written sources in 1309. At that time the present Gothic stone church must have been new. Judging by the style in the western portal and the eastern chancel windows, the church must have been built around 1300 or just before, probably by builders from Bergen influenced by the English Gothic style.
At the bottom of Vargavågen on Halhjem lies Grødalshaug, a 30 metres high rocky outcrop between the bay and a moist valley cleft. On the south side of the rock is a steep rock cliff facing the valley, the bog and the stream. On this rock face we find rock carvings from the Bronze Age.
Lysekloster was the largest agricultural property in the country when it was phased out during the Reformation in 1537. In its prime this cloister encompassed two-thirds of all the farms in Os. The monks introduced and cultivated new plant species and it was probably they who stocked the waters with fish not indigenous to the area. This legacy from the Middle Ages has left a lasting mark.
