Another subject in the Amsterdam Museum was about World War II. A little attic was created with a wooden box.
The box was supposed to be a storage for books. However it had a hidden secret, a radio was placed under in the box. The German occupiers had forbidden to have any radios at home. They were afraid you could hear any informations about their setbacks. Many people had anyway a hidden radio to listen at night to the BBC broadcasts and Radio Oranje (Orange), the dutch government radio in exile in London. Secret messages were passed on about the progresses of the allies. It was very dangerous to have a radio at home because the soldiers often came to search the houses and when a radio was found the owner was arrested, executed or send to one of the notorious camps.
Old Queen Wilhelmina speaking on Radio Oranje from London. In total she spoke a 34 times during the course of the war.
