The discovery of the Sanxingdui site provides unique physical evidence of the vanished ancient Shu kingdom, which dates back 4800 years. The new Sanxingdui Museum is located in the Archaeological Park and has a floor area of 35,000m2 , which will house the current and future excavations. The design adopts an innovative spatial mesh shell structure system, and the three stacked bases meet the structural form without columns, maximising the space in the exhibition hall to meet the needs of new archaeological discoveries and changing exhibitions.
