The history of the place dates back to the Middle Ages. The first temple, the Orthodox Church of the Mother of God founded by Prince Daniel Romanovich, existed here as early as the 13th century. Today’s basilica was built in the 18th century on the initiative of Bishop Philip Volodkovich, according to a design by architect Pavel Fontana.
