DASA Working World Exhibition (Dortmund)

Be sure to visit the DASA if you have the opportunity. The various themed exhibitions and actions of the DASA are very interesting and there is much to discover and even to marvel at. Definitively suitable for families with children!
Far too much to put everything in one tip, check out the website at dasa-dortmund.de.

Michael is right: the name may sound dröge: "German labor protection exhibition". In fact, museum-pedagogically excellent exhibitions on the history of occupational safety with accidents, illnesses, gradual improvements and setbacks. Not only technology, but also social and economic history. For students in the eastern Ruhr area a must, for the rest highly recommended. In addition, directly at the south exit of the S-Bfs. DO-Dorstfeld South and other highlights such as Uni with H-Bahn, Emschertal, Schnetkerbrücke nearby.

Both permanent and temporary exhibitions are recommended, even if some of the interactive pieces in the permanent exhibition are not always up to the onslaught of spectators and can then not be used for some time.
The construction site is definitely nice for younger children to be active themselves.
