Great insight into an impressive industrial complex. The inner workings are very well preserved and you can get up closeclose to see them.

It is a very interesting museum. It supports various languages.

This is a superb experience. Maybe not for very small children. It is a total steam punk paradise. Nice and weird subject: the region it lies in, in all it's aspects. You must have interest in old factories and nostalgic technology. Else it's not for you. You will see large halls of ancient machinery used to separate dirt from coal. Plus a view upon what the region has and had. I wouldn't not go on the guided tour: it takes two hours and half an hour would have been enough for the tour. The museum however, is gigantic. It takes almost all day just to walk through it. A walk around the buildings, as described on the available map, is highly recommended.

The exterior was interesting & the interior was designed well. However, I can't recommend the interior to families. I was asked to leave for nursing my four month old daughter! I was sent to a stairwell to nurse since the museum employee claimed my daughter could not have food or drink while I sat at a bench in the museum (away from exhibits). In the United States my right to breastfeed my child in public is protected. I thought Germany was more progressive and supportive of families. I'm incredibly disappointed in the museum's treatment of new mothers and families.

Spent most of the day here, firstly choosing to wander around the hugh grounds and then ducking into the Ruhr museum. Lots to see, not to mention the industrial architecture photography possibilities.
