The Center for Studies of Holocaust and Religious Minorities in Norway will use the Villa Grande for displays and research activities focusing on the Nazi-led genocide of 6 million Jews. It will also raise awareness about the persecution of other minorities.
Quisling was executed at the end of the war for setting up a puppet government that collaborated with German occupation forces. His name remains a synonym for traitor.
After Nazi troops invaded Norway in 1940 and Quisling proclaimed himself "Minister President", he picked Villa Grande as his home, and moved in with his wife, Maria, in 1941.
Five years ago, the government decided to restore the mansion and turn it over to the center as part of a settlement with the Nordic nation's Jewish community.
During the Quisling years, about one-third of Norway's prewar community of 2,100 Jews died in the Holocaust and much of their property was stolen.
In March 1999, parliament set aside NOK 450 million (USD 69 million) to compensate Jewish families for property stolen by the Nazis and to fund community projects. Of the total, NOK 40 million (USD 6.1 million) was earmarked for the center.
