Already at the beginning of the 1870s demands were made that there had to be a railway connection between Bergen and East Norway. The first section between Bergen and Voss was finished in 1883. The route alternatives further on were many: Lærdal-Valdres, Aurland-Geiteryggen, Raundalen-Finse and Ulvik-Finse. Following a long dispute, an agreement was finally reached that the middle route alternative, Raundalen- Myrdal- Finse, was the best alternative. In 1894 the government passed a resolution that the Bergen railway should be built, but only the section Voss-Taugevatn. This was a political gamble in order to make the rest of the country participate in the plans. In 1898 it was approved that the railway be continued eastwards from Taugevatn to Oslo. This high mountain project was one of the most challenging railway projects in Europe. The Bergen railway was to be built across a mountain plateau without roads.
Opponents of the Bergen Railway used the snow argument for all it was worth. During the debate in Parliament before the decision about the route was reached in 1894, fears of snowfalls of over 20 metres were presented.
Freezing and thawing are processes that influence plant cover, move enormous blocks, stretche long mounds of earth, break open bedrock and create patterns in stone and earth.
At the bottom of the Osa fjord there is a cultural landscape marked by great contrasts; the wide terraces and the river delta at the fjord contrast with the steep hillsides in the background, where Norddalen leads up to the mountain. There are two farms here. Osa and Sævartveit – the farm at the river mouth and the hollow by the sea.
Fyksesundet and Botnagrenda present a fine experience of the landscape and cultural history; a geographically isolated local settlement with extensive cultural contact with the outside world.
The farm Nes lies directly inside Mundheim on a forested headland in the fjord between Mundheimsvika and Bondesundet, a farm with an attractive and well-kept cultural landscape.
