National Monument Kamp Amersfoort is a museum focusing on the 47,000 people who were imprisoned in Kamp Amersfoort during World War II. It was the longest operating concentration camp in the German-occupied Netherlands.
By 2021, the underground museum was opened to include a permanent exhibition and an annually changing exhibition. Using objects, documents and visual material, the museum highlights the structural system of hunger, forced labour, beatings, transports and executions. The indoor area includes the original roll call clock and five wartime trees. In the outdoor area are several monuments and the Shooting Range, which was dug out by hand by prisoners. Near the museum entrance is an authentic watchtower.
