Our Lady of Kazan Our Lady of Kazan, also called Theotokos of Kazan, was a holy icon of the highest stature within the Russian Orthodox Church, representing the Virgin Mary as the protector and patroness of the city of Kazan. Copies of the image are also venerated in the Catholic Church. Her feast days are July 21 and November 4 (which is also the Day of National Unity). According to tradition, the icon was discovered on July 8, 1579, underground in the city of Kazan by a little girl, Matrona, to whom the location of the image was revealed by the Theotokos, the Blessed Virgin Mary, in a Marian apparition. The original icon was kept in the Theotokos Monastery of Kazan, built to commemorate the spot where it had been discovered.
