MuMa-Forum, Film museum in Stieghorst, Bielefeld, Germany.
The MuMa-Forum is a film museum in Bielefeld dedicated to the history and technology of cinema. The space displays collections of analog and digital films across a large exhibition area and features a working cinema room.
The museum was founded in 2022 and honors the legacy of two influential filmmakers from the region. This establishment connects local film history with contemporary museum practice.
The museum's own cinema screens analog and digital films, including early sound films from 1929 to 1932 and 1950s–60s Kulturfilme restored by the Tri-Ergon Filmwerk foundation with FFA funds. These Kulturfilme were once booked so distributors and cinema owners could avoid the entertainment tax levied on programmes without an FBW rating; audiences for films like Schulmädchen-Report thus saw them unintentionally.
The museum has been closed since June 2025, when its operator filed for insolvency over rent debt for the building, so check its status before planning a visit. The permanent exhibition occupied about 1,250 m². The MuMa-Forum is in Bielefeld's Stieghorst district, not in Hillegossen.
The museum's backers are film professionals who once projected analog films at Bielefeld's Kamera Filmkunsttheater; they pass on how analog and digital projection works. Since June 2025 the building's rent debt forced the operator to file for insolvency, and the museum has been closed since then.
