Pugong Mountain in Henan Province is a limestone mountain. Over the decades, local residents have built hundreds of small lime kilns to produce lime. Residents quickly became rich, but the environment was badly damaged. After the introduction of the national environmental protection policy, the site has become an abandoned gypsum mine site. To promote the idea o f sustainable development, we were invited to design the museum. We integrated the new and old plaster kiln together, taking the old kiln group as a whole relic park landmark door, transforming the kiln head for viewing platform, setting one of the old kilns as the museum's main entrance, making the mine, old plaster kiln and the new museum as an organic whole. We set several key mining sites from the original mine site as ecological education sites, and set observation windows and viewing platforms at the corresponding positions of the museum building, so that the museum building is closely anchored in this special place.
