Harbin St. Sophia Cathedral (哈尔滨圣索非亚教堂) is one of the few still standing Orthodox churches in the city. Currently it had been converted into a Harbin Museum of Architecture. There are some exhibitions of many photographs from the old days of Harbin inside. Entrance ticket is RMB20 per adult. Inside the building was quite badly maintained with the paints on the wall were coming off. Still it is one nice Russian inspired architecture left standing in the cold city of Harbin.
