Along with small everyday items, much bigger things can also be upcycled—even old buildings that cannot be used for their original purpose anymore. The German government showed us an excellent example of this with a former steel plant that closed in 1985. Rather than destroy the plant's buildings or abandon the entire facility, they decided to give it new meaning as a series of useful public structures. Many of the buildings kept their original shapes, but received extra equipment and new designs in their surrounding areas. For instance, old gas tanks became pools for divers. Concrete walls of iron storage towers were turned into ideal training fields for rock climbers. Can you believe a building for melting metal is now a viewing platform with a gorgeous 360-degree view? The final result is the Landscape Park Duisburg Nord. It has almost 570 acres of land filled with gardens, cycling paths, and pretty lights at night, in addition to its creatively repurposed buildings. This park proves that it’s possible to preserve the heritage of a place as well as the environment.
