Initially, today's Annunciation Cathedral had just three domes. After being badly damaged in a fire again in 1547, the then Grand Duke and (the first Russian Tsar) Ivan the Terrible began a restoration of the church, which was completed in 1564. Two additional domes were added on the western side. The building was surrounded by parvises from three sides, and four single-cupola side chapels were built over the arched parvises, each with a dome, so that the cathedral is now a total of nine domes. In 1572, the cathedral received an additional staircase on its south facade, later called "Grosnenski"), named after Ivan the Terrible (Russian for "Ivan Grozny").
