That's quite hard because Duisburg has tons of art, a lot of it in obscure parts of the city. And a lot of the sculptures don't have any helpful plaques or something like that, so quite a bit of research is required. I used to go on tons of walks during the height of the pandemic and when the kids were smaller to find sculptures.

There's a book from the 1980s that catalogues the public art here, but all the newer stuff isn't in there of course.

Anyway, the sculpture I was looking for is from 2022 and called "Emscher Folly", by Nicole Wermers. It's in the still quite industrial northern part of the city. It can be reached with a bike path that's between a steel plant and a wastewater treatment plant. To get to the start of the bike path you need to go through pretty industrial areas already.

This building is the pumping station of the old Emscher, opened in 1914. The Emscher is the second river (after the Ruhr) that flows through large parts of the Ruhr area. Due to all the mining activity, large parts of the ground sank down, so the Emscher doesn't flow into the Rhine on its own any more. The place where it gets pumped into the Rhine changed a few times, now it's further north. The pumping station isn't operational any more but maybe can be turned on in emergencies?

A bit behind the pumping station, the bike path starts, with some nice wild garbage (this used to me a camper trailer I think?). And a bit behind that, a few other sculptures that I wasn't really specifically looking for. None of these had plaques or any useful information about them, but I later found out by Googling carefully that they were designed by groups of art students as part of Emscherkunst.2013 when the bike path was being planned.
