Since the Christianization of Lithuania in 1387, Vilnius has become one of the main centres of Christianity in Lithuania and a Christian pilgrimage site. Vilnius Pilgrimage Centre () coordinates pilgrimages, assists in their proper preparation, and takes care of pilgrimage pastoral care. Many places in Vilnius are associated with divine miracles or marks significant events to the Christians. The Chapel of the Gate of Dawn is visited by thousands of Christian pilgrims annually. Initially, the gates were part of the defensive Wall of Vilnius, however in the 16th century they were given to the Carmelites, who installed a chapel in the gates with a prominent 17th century Catholic painting Our Lady of the Gate of Dawn. The painting was later decorated with gold-plated silver embellishments and is surrounded by a legend and divine miracles.
