The Cathedral of Holy Wisdom in Polotsk was built by Prince Vseslav Briacheslavich between 1044 and 1066. It stands at the confluence of the Polota and Western Dvina Rivers on the eastern side of the city and is probably the oldest church in Belarus.
The cathedral is, like the Saint Sophia Cathedral in Kiev and Saint Sophia Cathedral in Novgorod, named after the Holy Wisdom of God. After building his own cathedral, Vseslav, who was an izgoi prince, tried to seize the Kievan throne. Failing in that attempt, he raided the surrounding principalities; in 1067, he raided Novgorod the Great and looted the Cathedral of Holy Wisdom there, bringing a bell and other loot back to decorate his own Cathedral of Holy Wisdom. The cathedral is mentioned in The Tale of Igor's Campaign, where it says that Vseslav would make nocturnal trips to Kiev as a werewolf and would hear the bells of Holy Wisdom at Polotsk as they rang for matins.
