Lurekalven
Lurekalven is an unpopulated island of heather moor which is a part of the wilderness belonging to the five farms on Ytre Lygra. Between the two islands there is only a small sound. As late as the 1920s, milking cows were rowed over the sound from Lygra in summer – a form of farming that was adapted to the coastal landscape.
Seim
Sæheim (Seim) at Lygrefjord is mentioned as one of the royal farms of Harald Hårfagre. Several of the first Norwegian national kings had their seat here, and the farm became Crown Property up to the 1400s. According to the sagas, Håkon den gode is buried on the farm.
Herlandsnesjane
Herlandsnesjane, a four-kilometre long peninsula in Lake Storavatnet in the middle of Osterøy, is well known among botanists. Here lies an unusually large and diverse bog.
