The outer wall decoration of Ningbo Museum is made in two ways. Some walls are decorated by millions of tiles collected in local areas. This sort of decoration itself was a common way of building an economical house in old days in Ningbo when cements are not introduced. Other walls are decorated with cement-covered bamboos.[1] It is reported that Ningbo Museum was the first museum built with large number of used materials.[2] Ningbo Tengtou Pavilion in Shanghai World Expo also employed the similar decoration.[3]
