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.
The prehistoric site at Årbakkasanden with menhirs and burial mounds has been visited, described and illustrated by many learned researchers through the last 350 years. All the same, we still know very little of this unique cultural monument.
