St. Alexius Church, Harbin, Catholic church in Nangang District, Harbin, China

St. Alexius Church is a brick church with a Baroque design, built in 1931–1935 on Shike Street. Its central dome rests on four columns, and the interior holds religious paintings by the icon painter Sadrozhini. The church can hold 1,500 people and was originally Orthodox, now Catholic.

The wooden church came from a Russian military chapel in Gongzhuling and was moved to Modaogou in 1912; a bell tower followed in 1913. The stone church was begun in September 1930 on the corner of Tserkovnaya and Skobelevskaya streets, designed by Yu. V. Smirnov and supervised by engineer Mikhail Karbyshev, with the project revised in 1934 by Boris Tustanovsky. It was consecrated on 6 October 1935.

Since 25 December 1980 the building has served Harbin's Catholic community as the Church of the Immaculate Conception, after the Sacred Heart cathedral on Dongdazhi Street was damaged. The interior keeps religious paintings and a Madonna image attributed to the church painter Sadrokhini, and the former Orthodox church is now a provincial cultural relic.

The church is located in a neighborhood that you can reach by foot or by using local transportation options. Visitors should approach with respect since active religious services take place at the site.

The church closed in 1956, and much of its liturgical silver and vessels were carried by graduates of the Chinese Eastern Railway schools to San Francisco, where they are kept in the Joy of All Who Sorrow Cathedral. The last rector, protopriest Stefan Wu, was executed in 1970 and buried in Harbin's Huangshan Orthodox cemetery.
