The Cathedral of the Immaculate Conception (圣母无染原罪始胎堂), commonly known as Shigu Road Cathedral (石鼓路天主教堂) to the locals, is a late 19th-century church in Nanjing that serves as the cathedral of the Roman Catholic Archdiocese of Nanking. It is located in the centre of the city at 112 Shigu Road. First built in 1870 during the Qing dynasty, it was later severely damaged during the Northern Expedition War and had to be rebuilt by the Chinese government in 1928. Since the 1930s it has served as the cathedral for the Archdiocese of Nanjing and is the only Catholic church within the city of Nanjing today. In 1982 it was also listed as a Jiangsu Provincial Historic Site.
