Krossøy
Furthest north in the island community Rongevær, at the entrance to Fensfjorden, lies Krossøy. Belonging to the farm are the islands of Krossøy, Husøy, Kårøy, Lyngkjerringa, Søre Kjerringa, Rotøy and Kuhovet. All of them have been inhabited. On Krossøy itself today there are four holdings. The marine use environment here is one of the best preserved along the West Norwegian coast.
Litlandsvatnet
Large quantities of nickel ore have been mined from Litlandsvatnet, between Lonevågen and Hosanger. The discovery was made in 1875. During the period of operation from 1882 to 1945, 4170 tonnes of pure nickel were extracted from 462 000 tonnes of ore, a large production by Norwegian standards.
Mjøsvågen
Around Mjøsvågen here is still a compact marine use area. Some of the buildings are common boathouses, but most of them also house small enterprises and workshops. This is where the farmers from Øvsthus, Mjøs, Hole and other farms have supplemented their meagre incomes as smiths, brass moulders, clog makers, chest builders and decorative painters.
Gåssand
The 28th November 1914 was a day to remember for the Os inhabitants. This was the day they could turn the switch on the wall and have electric light in their houses. It was like opening the door on the future when the power station at Gåssand was put into operation.
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.
