This memorial hall for the May 12th geological disaster is located in Dujiangyan, Sichuan, China. By the Min River, the site blends with nature while preserving the memory of the 2008 earthquake. The design, inspired by a fallen leaf, consists of five interconnected buildings: a memorial exhibition hall, a medical and healing unit, a lecture hall, a commercial area, and logistics space. A Möbius roof unifies the structures, emphasizing organic integration. Using local wood, the design ensures structural integrity while reflecting regional character.
