The Cathedral of Holy Wisdom in Polotsk (Belarusian: Полацкі Сафійскі сабор; Russian: Собор Святой Софии в Полоцке) was built by Prince Vseslav Briacheslavich (rr.1044–1101) between 1044 (it is first mentioned in the Voskresenskaia Chronicle under the year 1056) 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.
