Four years after Anders Behring Breivik’s terrorist attack left 69 people, many of whom were teenagers, dead on the island of Utøya, the controversial memorial to the victims has been finished.

Breivik’s attacks, which included a bomb that killed a further eight people in Oslo, took place on July 22nd, 2011.

Now a memorial ring, weighing half a tonne, has been suspended in a clearing on the island where the 69 dead, the youngest of whom were just 14 years old, were gunned down. The ring is engraved with the names of all of those who died on Utøya that day.

Named Lysningen (the Norwegian for ‘The Clearing’), the art piece was designed by 3RW, an architecture firm based in Bergen. The final memorial was chosen by a group of survivors and parents of the victims, after the original one selected became embroiled in ongoing controversy, with local community members describing it as a “rape of the land.”

Memory Wound, a project created by Swedish artist Jonas Dahlberg, was well received by artists and media around the world when it was chosen in March 2014. The artwork proposed carving a three-and-a-half-meter wide slice out of the Sørbråten peninsula, which juts out of the Norwegian mainland towards Utøya.

Local groups rallied against the plans, saying that it would create a “permanent scar” on the coastal landscape, and the Norwegian government backed down, offering four other memorial options to a steering group made up of survivors and the bereaved.

Speaking to Norway’s national broadcaster, NRK, Kolbein Fridtun, whose daughter Hanne Kristine was killed by Breivik, described the newly-finished artwork as something for everyone.

“This memorial is for survivors who lost their loved ones on Utøya, but also for all other visitors,” he said. “I get a lump in my throat when I stand here. It is perhaps not surprising, because my daughter's name is hanging here on the ring.”

An open day is currently taking place on Utøya for visitors to pay their respects to the dead and see the memorial, which will be officially opened on the fourth anniversary of Breivik’s attack.

Breivik is currently two years into his 21-year prison stretch, the longest possible sentence that can be imposed under Norwegian law. He is in permanent solitary confinement, and is currently suing the Norwegian government, claiming his prison conditions constitute a breach of his human rights.
