The construction of the national memorial site began last autumn and the plan is for the monument to consist of 77 three-meter-high bronze pillars, a pillar for each of those who died in the terrorist attack in 2011.
The process of deciding where the memorial site should be has been long.
Almost four years ago, the memorial site was moved from Sørbråten because the resistance from the neighbors there was so strong.
The new place chosen was Utøyakaia, which is owned by the Norwegian Labor Party's youth union.
But some of Utøyakaya's neighbors reacted strongly and sued the state and the Norwegian Labor Party's youth union (AUF).
Strong feelings
The trial has been marked by strong emotions.
Several of the neighbors behind the atmosphere were involved in rescuing young people in the terrorist attack.
They want to stop the construction of the memorial site because they believe that having the memorial as their nearest neighbor will cause them mental suffering
- We are shocked and infinitely disappointed with the district court's decision.
We will review the verdict with our lawyer and come back with further comments, says Anne-Gry Ruud, spokesperson for the plaintiffs.
"Means a lot for survivors and relatives"
AUF thinks it is important to have a memorial site and hopes that the ruling can put an end to the debate about the memorial site.
- We are satisfied and relieved after the district court's decision.
A national memorial on Utøyakaia means a lot to survivors, survivors and relatives.
The decision means that the memorial site will be ready for the tenth anniversary on July 22 this year, says AUF's general secretary Sindre Lysø to NRK.
The neighbors will not have to pay the costs.
The district court justifies this with the case's very special prehistory and lack of case law.
The neighbors who lost have a month to appeal the verdict.
