I had a good experience while learning the history of the area. If you have a local friend or tour…read moreguide, you can spend a couple hours walking around the facility/park. You'll get a beautiful industrial view in addition to public displays, cafes, and museum. Regardless of what day you visit, you'll find plenty of frequent visitors, but will also find good spots to relax alone. I recommend this spot for engineers, those curious of Essen's history, and others who want to sight-see. You'll also find Germany's longest escalator nearby on the way to the museum.
