The Memorial Hall of the First National Congress Site of the CPC is located at the city of Shanghai. The buildings of the memorial hall are two rows of nineShikumen(a kind of typical residential two-storeyed building popular in the late early 20thcentury in Shanghai) buildings with the total space of 900 square meters.

In October 1951, the Administrative Committee of Shanghai Revolutionary Historical Memorial Hall confirmed the site and had it open restrictedly after a little renovation. In 1958, the original features of the Congress Site were restored and several auxiliary exhibition rooms were arranged in the houses adjoining the Congress Site. In March 1961, the State Council of the People's Republic of China declared it a major historical site under the State protection. It was not until in 1967 that it was officially named the Memorial Hall of 1^stNational Congress Site of the CPC.

The meeting room of the 1^stNational Congress used to be the parlor of the residence of Li Hanjun (original name as Li Shushi), one of the Shanghai representatives participating in the 1^stNational Congress, and his elder brother Li Shucheng. On July 23, 1921, the congress of founding the CPC was held here. The Congress Site was only an 18 square meters room with tea sets, vases and ashtrays laid on the big dining table in the center. The long table is surrounded with round stools and square chairs for the representatives to sit, a small two-drawer desk is laid by the wooden partition at the north end and the old-style lampshades and tungsten lamps are used for room illumination. All these arrangements are drawn and reproduced in accordance with the memory of Ms. Xue Wenshu, Li Shucheng's wife, the owner of the building, and examined and approved on the spot by Dong Biwu, Li Da and Bao Huiseng, the representatives of the 1^stNational Congress. The show rooms behind the Congress Site consist of three parts, namely the Historical Background of Founding of the CPC, the Birth and Activities of Communist Groups in Various Places, and the Birth of the CPC. The photos, historical data and objects, totaling around 200 items, in the 90 square metersshow rooms reappear the history at the time of establishment of the CPC. The existing display also shows the photos and biographical notes of all the thirteen representatives and the two Comintern representatives present at the 1^stNational Congress.
