[1] Bishop Elias of Polotsk tasked Euphrosyne with setting up a women's monastery[2] and she settled near the Transfiguration church in Selce.

Members of the monastery taught young women to copy books, sing, sew and do other handicrafts.

[3] In 1161, with the zeal of St. Euphrosyne the Monk the stone Transfiguration Church was erected, the best preserved monument of the ancient Polotsk architecture.

In the XIII century the cross was taken from Polotsk, but again returned to the monastery Ivan the Terrible in 1563 after the successful siege of the city.

In 1941, during the Great Patriotic War, the Cross of Euphrosyne of Polotsk disappeared without a trace and has not yet been found.
