Pugong Mountain in Henan Province is a limestone mountain where local residents built hundreds of small lime kilns to produce lime to quickly get rich, but the environment has been severely damaged and the site is now abandoned. Based on the concept of sustainable development, we take the old kiln group as a symbolic gate, and transform the kiln head into a viewing platform, so that the mine, the old gypsum kiln and the new museum are an organic whole, and several key mining areas are set as ecological Education point, and setting viewing windows in the corresponding position of the building.
