Sverd i Fjell - The battle of Hafrsfjord

Please allow me some very basic Norwegian history.

The first king of Norway (probably Harald something...sorry I'm just French :-)) in year 872 won a naval battle in the fjord of Hafrsfjord which resulted in the unity of Norway into one kingdom.

The Swords is a monument representing that battle and raised in 1983 at the northernmost end of Hafrsfjord.

PS: For more details, don't ask the French guy ;-)
