Hohenhof, Art Nouveau villa in Eppenhausen, Hagen, Germany

Hohenhof is a 1906–1908 Art Nouveau villa in Eppenhausen, Hagen, designed by Henry van de Velde for Karl Ernst Osthaus. Its grey stone and slate walls carry a rounded bay with a row of windows, four round dormer windows in the slate roof, and a projecting dark stone entrance porch reached by stone steps. Tall grilles protect windows to the right of the door.

Henry van de Velde designed the villa for Karl Ernst Osthaus and his wife Gertrud; it was built between 1906 and 1908 within the Gartenstadt Hohenhagen. In 1927 the family sold building and grounds to the city of Hagen on condition that the ensemble be kept as a Gesamtkunstwerk. From 1933 the city gave it to the NSDAP for a Gauführerschule; it served as a military hospital at the war's end and as a women's clinic from 1946 to 1962.

The villa was conceived as a Gesamtkunstwerk, with Henry van de Velde designing the shell, furnishings and garden as one work. The name Hohenhof comes from the Hohenhagen garden city Osthaus laid out around it. Today it is an anchor point on the Route der Industriekultur and one of the Karl-Ernst-Osthaus-Museum's two sites in Hagen.

Hohenhof is an anchor point on the Route der Industriekultur and one of the two sites of the Karl-Ernst-Osthaus-Museum, alongside the Kunstquartier. It stands in the Gartenstadt Hohenhagen in Hagen-Eppenhausen, southeast of the city centre on the edge of the Ruhr. The historic garden is being returned to its state of around 1910/13 as part of the "Villa Hohenhof" project for the IGA 2027, with work under way since 2022.

The villa is an anchor point on the Route der Industriekultur, the Ruhr's industrial heritage trail. From 1924 to 1930 its rooms housed the Handweberei Hohenhagen, a hand-weaving workshop run by Eberhard Osthaus and Horst and Evangeline Helbing, which moved to Bremen in 1930.
