Vangdal
At Salthamaren in Vangdalsberget it is thought that salt was burned some time in history, and deep layers of coal in the ground show that fire has been made up here several times. But they were hardly salt-burners, the first people who stopped here. Some of them carved figures into the rock. On top of the rocky outcrop, furthest out on the cliff, a group of Stone Age hunters carved animal figures. More than 1,500 years later Bronze Age farmers drew ship figures at the foot of the rock. Both these works of art - some of the oldest in Hordaland – are still visible, carved in the rock at Salthamaren.
Valldalen
Valldalen or Valdalen, the name that the locals used in past times, had been a permanent settlement for a long time, and later the biggest mountain-farm valley in western Norway. Since that time there have been many changes: Most of the fields are no longer in use. Bjørkeskogen, a birch forest that had grown in the valley for thousands of years, took more and more over. And in the valley bottom, the Valldals dam now keeps the artificially large Valldalsvatnet Lake in place.
Ullensvang church
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.
Grødalshaug
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- The monks and nature
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.
