The Cathederal of the Annunciation, (Blagoveshchenskiy sobor), detail of the golden domes. This served as a private church if the Grand Dukes and Tsars. The existing structure was erected in 1448-49 but was badly damaged in 1547 and restored again in 1562-64. When Ivan the Terrible married for the fourth time, contrary to the rules of the Orthodox faith, which allowed onlt three marriages, a fourth covered porch was added in 1572 at the northeast corner. This is the smallest of the three cathederals in the Kremlin but the most ornate.
