On this site in Frederiksberg stood The French School or also known as Institut Jeanne d’Arc. It was hit by bombs during the controversial british Operation Carthage raid against the SS Headquarter Shell-Huset in Copenhagen on March 21st. 1945.
In the school were 529 people. 482 children, 34 katholic nunns, 8 civil teachers and 5 parent or workers. 87 children and 13 adults, mostly nunns, were killed at the raid.
Today a memorial stands on the site (placemark). After the war the ground was cleared and blocks of flats were build.
