The cathedrals of the Donskoy Monastery are home to the richest collection of religious relics connected to some of the most significant events in Russian history. From the moment of its foundation, a copy of the Our Lady of Kazan icon, which aided the Russian army in its victory over the Tatars, has been kept in the monastery’s main cathedral. The necropolis of the royal Bagrationi dynasty is also located in the cathedral’s basement. The monastery’s Maly Cathedral is fascinating for its own reason — it is here in 1992 that once-believed lost relics of St. Tikhon, Patriarch of Russia, were found.
