Herinneringscentrum Kamp Westerbork (Memorial Center Camp Westerbork) in Hooghalen was built in 1983. It was the result of a private initiative combined with financial support from the Dutch government. The museum houses a permanent exhibition on the history of camp Westerbork, with many original photographs, documents, drawings, paintings, images, maps, and objects from Westerbork. The documentation centre houses a collection of books, documents, photographs, and videotapes, which are all available for research. Visitors can consult the Memorial Books of the Oorlogsgravenstichting (War Graves Foundation). They record the names of more than 140,000 Dutchmen who were killed during World War II and who did not receive a proper burial.
