The Deutsche Bergbau Museum in Bochum with its 68 m high observation tower/head-frame was founded in 1930 and deals with the historical development of the different areas of mining.

The extensive collection "Mining in Art and Cultural History" serves as a connecting link. The model mine (the gallery is 3 km long) gives a vivid impression of modern mining methods
