Architecture, Building and Structure Design Pingyuan Mysterious Stone Art Museum by Tengyuan Design Pingyuan Mysterious Stone Art is a museum for the exhibition and trade of rare stones. The building stands on a quiet site, with the eastern side facing a stone garden and open plains along the rest of the perimeter. The museum is shaped as one large stone divided into four parts, each holding a separate exhibition. A central atrium with skylights links the four halls and forms a circular visitor route. The main facade is made of stone panels, while large glass areas and an overhanging structure open the southern and eastern sides. A public terrace offers views toward the stone garden.
