Boris Stones (Belarusian: Барысавы камяні, [baˈrɨsavɨ kamʲaˈni]; Russian: Борисовы камни), also called Dvina Stones (Russian: Двинские камни), are seven medieval artifacts erected along the bank of the Western Dvina between Polotsk and Drissa, Belarus. They probably predate Christianity in the area, but were inscribed in the 12th century with text and an image of Christ. The largest of the stones is 17 metres in circumference.
