11 Forgotten Industrial Ruins That Are Now Unique Art Installations

9. Cementland (Conceptual), St. Louis, USA: Sculptor's Industrial Playground

The late Bob Cassilly's unfinished magnum opus, built in an abandoned cement factory, aimed to be a sprawling landscape of repurposed industrial machinery, concrete structures, and climbable sculptures. Though incomplete and tragically marred, its vision was ingenious: transforming the detritus of industry – kilns, silos, conveyors – into a fantastical, interactive art environment. It represents the ultimate artist-driven reclamation, seeing potential for play and wonder not despite the industrial ruin, but because of it, envisioning a surreal playground built from the bones of production.
