The world's largest mining museum, founded 1930 in Bochum, with a visitor mine, four permanent exhibition tours, and a landmark 71.4-metre headframe from the former Zeche Germania.
The Deutsches Bergbau-Museum Bochum is the world's largest mining museum, founded on 1 April 1930 through an agreement between the Westfälische Berggewerkschaftskasse (WBK) and the city of Bochum. Its origins trace back to 1868, when the WBK established a permanent display of mining utensils for use in Bochum's mining school. The founding museum occupied an old abattoir hall before a purpose-built building designed by Fritz Schupp and Heinrich Holzapfel was erected on the site between 1935 and 1942.
In 1973 the 71.4-metre double headframe from the decommissioned Zeche Germania in Dortmund-Marten was relocated to Bochum and erected above the museum, becoming the city's most recognisable landmark. The museum was renamed Deutsches Bergbau-Museum Bochum on 1 March 1976 and was recognised as a research museum in 1977, joining the Leibniz Association. A south annex opened in 1986 and a further annex named the Schwarzer Diamant in 2009.
Following a comprehensive renovation from 2016 to 2019, the museum reopened with a redesigned permanent exhibition comprising four tours. The headframe was conserved and illuminated in a further restoration completed in early 2024.
The roots of the Deutsches Bergbau-Museum Bochum reach back to 1868, when the Westfälische Berggewerkschaftskasse (WBK) created a permanent display of mining utensils at Bochum, primarily serving as teaching material for the adjacent mining school (the institution now known as the THGA Bochum). This display, continuously expanded over the following decades, formed the nucleus of what would become the museum's collections. By the late 1920s representatives of the WBK and the city of Bochum were developing plans for a publicly accessible mining museum.
The founding agreement for what was then called the Geschichtliches Museum des Bergbaus was signed on 1 April 1930 between the city of Bochum and the WBK. The museum's first hall was accommodated in the old large-animal slaughterhouse of the defunct Bochum abattoir. Between 1935 and 1942 a purpose-built museum building was erected to designs by the industrial architects Fritz Schupp and Heinrich Holzapfel; the structure's formal language, with cubic volumes, tall rectangular windows, and emphasised corners, reflects the industrial building idiom of the period, with the entrance area also bearing characteristics of the aesthetic preferences of the National Socialist period.
In 1973 and 1974 the 71.4-metre double-strut headframe from the decommissioned Zeche Germania in Dortmund-Marten was dismantled and transported to Bochum, where it was re-erected over the museum site. The headframe, designed by Fritz Schupp and Martin Kremmer and built in 1943–44, was at the time of its construction reckoned to be the largest headframe in the world; it weighs 650 tonnes and has sheave wheels of 8 metres diameter. Its relocation to Bochum was funded from the budget of the North Rhine-Westphalian cultural ministry.
The headframe's rescue triggered a broader public debate about the preservation of industrial heritage monuments. In 1974 the Geological Museum of the Ruhr coalfield was transferred from the WBK to the museum. Visitor numbers exceeded 300,000 for the first time in 1974, with 317,000 recorded.
On 1 March 1976 the museum was renamed the Deutsches Bergbau-Museum Bochum to reflect its national significance. In 1977 it was recognised as a research museum by the Bund-Länder-Kommission and included in the joint national-regional research funding programme, joining the institutions on the Blaue Liste, now the Leibniz Association. In 1979 the museum was admitted to the Arbeitsgemeinschaft außeruniversitärer historischer Forschungseinrichtungen in der Bundesrepublik Deutschland.
In 1980 the museum celebrated its 50th anniversary. The Bergbau-Archiv Bochum had been established on 1 July 1969 by the DMT-Gesellschaft für Lehre und Bildung mbH, the Wirtschaftsvereinigung Bergbau, and the Gesamtverband Steinkohle to preserve the written heritage of the German mining industry; it subsequently became closely associated with the museum. In 1986 the Erweiterungsbau Süd (south annex) was opened, providing an additional 3,000 square metres of exhibition space together with an auditorium, seminar room, cafeteria, and restaurant.
From 1987 a series of large temporary exhibitions under director Rainer Slotta raised the museum's national profile. An iron ore mine section was added to the visitor mine in 1987, and in 2003 a modern longwall face was opened in the visitor mine after ten years of construction, making the Deutsches Bergbau-Museum the only mining museum in Germany to document the current state of hard coal mining technology underground. By 2005 the collections comprised over a quarter of a million objects.
In 2009 the Schwarzer Diamant annex, a deep-black building designed by Bentheim Crouwel Architekten whose geometric form represents a cross-section through a mine tunnel, was opened to provide space for special exhibitions; it also houses the Barbara Collection. The collections of the Bergbau-Archiv, the library, and the Fotothek were consolidated into the Montanhistorisches Dokumentationszentrum (montan.dok). A comprehensive renovation of the museum building and redesign of the permanent exhibition was carried out between 2016 and 2019.
The reopened museum presents four permanent exhibition tours — Steinkohle (Hard Coal), Bergbau (Mining), Bodenschätze (Mineral Resources), and Kunst (Art) — with over 3,000 exhibits. Interactive, multimedia, and hands-on elements were introduced throughout. The visitor mine, approximately 2.5 kilometres in total length with 1.2 kilometres accessible to visitors, offers a simulation of underground hard coal and iron ore working, including a pit descent simulator.
The headframe's two public viewing platforms are accessible by lift and stairs. The headframe underwent a further major conservation and restoration project completed in early 2024, after which it was equipped with a new LED lighting system enabling it to be illuminated at night.
