Annunciation Cathedral, Kazan (must see)

Originally a wooden church replaced by a stone sanctuary, the Annunciation Cathedral was founded in 1552 and was the first Christian cathedral inside the walls of the Kazan Kremlin. Being one of Kazan’s oldest surviving monuments and architectures, the church was named after the Annunciation of the Most Holy Virgin and Ivan himself marked this site with a cross. Over the centuries it suffered fire damage, with heavy restoration of the exterior as well as new altars, cupolas and iconostasis, an exact replica of the original, added. The new cathedral, established in 1562, contains two side altars, the right one in honor of Saints Boris and Gleb, and the left in honor of the miracle workers, Peter and Fevroniya.
