Nanjing Museum is located inside the Zhongshan Gate at the southern foot of Zijin Mountain as a famous museum of art and history. Originally named "Preparatory Committee of National Central Museum", it was first built in 1933 on the proposal of Mr. Cai Yuanpei. The name was changed to Nanjing Museum in March 1950. It now houses 420,000 pieces of cultural relics from ancient China to the modern time.
