Waalsdorpervlakte
The Waalsdorpervlakte is an open place in the dune area "Meijendel" ( The Hague, the Netherlands), where over 250 members of the Dutch resistance were killed by the Germans during World War II. It is also the site of top Nazi collaborator Anton Mussert's execution in 1946, a year after his arrest in The Hague on 7 May 1945. It is regarded one of the main locations where on 4 May " Remembrance of the Dead", a yearly commemoration of victims of World War II and other victims of war, is held.
