The Saint Sophia Cathedral is located in Toulong Street in Harbin. Built in 1907, it used to be the army cathedral of the East Siberia Fourth Infantry Division of Russia. It is a witness of Tsarist Russia's invasion to China. This masonry-timber structured cathedral covers an area of 721 square meters, with a height of 53.35 meters. Now it is a landmark of Harbin. Covered with snow, the Saint Sophia Cathedral is more like a castle in fairy tales. (Photo/people.cn)
