Sverd i fjell (Swords in Mountain), Hafrsfjord, Norway. You really should go and see them some day, they are larger than they seem. A perfect type of public art, as opposed to most new “expressionist” (etc.) creations made these days.
In any case, the monument was unveiled by King Olav in 1983 and commemorates the Battle of Hafrsfjord in 872. The swords represent the different districts that took part in the battle.
