De Hoop was built in 1846. In 1900, a steam engine was installed. This was replaced by a petrol engine in 1910. The mill ceased working by wind in 1931, after which its condition deteriorated. The mill was restored in 1951 by Beyk of Afferden, Gelderland, but not to working order. The mill was bought by the Gemeente Arnhem in 1975. In 1977, the mill was restored to working order, and officially opened on National Mills Day, 1978. In January 1999, the mill was registered as a place where weddings may take place. The Molen van Sloten, Sloten, North Holland is the only other windmill in the Netherlands to be so registered. De Hoop is listed as a Rijksmonument, № 8387.
