Christian feast day: Our Lady of Kazan (Russian Orthodox Church)

Our Lady of Kazan, also called Mother of God of Kazan, is 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, and a palladium of all of Russia and Rus', known as the Holy Protectress of Russia. As is the case for any holy entity under a Patriarchate in communion within the greater Eastern Orthodox Church, it is venerated by all Orthodox faithful.

The Russian Orthodox Church, also officially known as the Moscow Patriarchate, is an autocephalous Eastern Orthodox Christian church. It has 194 dioceses inside Russia. The primate of the ROC is the patriarch of Moscow and all Rus'.
