Cathedral of the Immaculate Conception, Roman Catholic cathedral in Nanjing, China

The Cathedral of the Immaculate Conception, known locally as Shigu Road Cathedral, is a Romanesque-style church with a cruciform plan, rounded arches, a bell tower, and a roof of timber trusses covered with iron sheets. Its interior ceiling uses curved wooden members and plaster laths to imitate Romanesque vaulting, a technique adopted because of limited access to Western materials and skills.

The building was constructed in 1870 during the Qing dynasty on ground with an important religious past dating back to the late 1500s. Following severe damage during military conflict in the late 1920s, the structure underwent major reconstruction to bring it back to full use.

The cathedral is commonly called Shigu Road Cathedral by locals, after its address at 112 Shigu Road. Since the 1930s it has served as the seat of the Catholic Archdiocese of Nanjing, and it is the only Catholic church within the city today. Masses are held for the local Catholic community.

The cathedral is located in the city center and relatively easy to find, with its tall tower serving as a good landmark from a distance. Visitors should be aware that active religious services take place there and should follow guidelines for respectful behavior inside.

The site where the church stands has been a place of worship since the late 1500s, marking one of the earliest centers of organized Christianity in the region. This continuous use across centuries makes the location a rare record of China's religious diversity.
