The Cathedral of the Immaculate Conception (Chinese: 圣母无染原罪堂), colloquially known as the Xuanwumen church (Chinese: 宣武门天主堂; pinyin: Xuānwǔmén Tiānzhǔtáng) or Nantang (Chinese: 南堂; literally: "the South Church") to the locals, is a historic Roman Catholic Church located in Beijing, China. While the original foundation of the cathedral was in 1605, making it the oldest Catholic church in Beijing, the current building in Baroque style dates from 1904. The present Archbishop Joseph Li Shan, installed in September 2007, is one of the few bishops openly recognized by both the Chinese Patriotic Catholic Church and the Vatican.
