The monument was created by sculptor Fritz Røed from Bryne and was unveiled by King Olav V of Norway in 1983.
The three bronze swords stand 10 metres (33 ft) tall and are planted into the rock of a small hill next to the fjord.
They commemorate the historic Battle of Hafrsfjord which by tradition took place there in the year 872, when King Harald Fairhair gathered all of Norway under one crown.
The largest sword represents the victorious Harald, and the two smaller swords represent the defeated petty kings. The monument also represents peace, since the swords are planted into solid rock, so they may never be removed.
