The &quot;Moscow Kremlin&quot; Fabergé Egg: Presented by Nicholas to Alexandra in 1906. By far the largest of the eggs, it was inspired by the Cathedral of the Assumption (Uspenski) in Moscow, where all the Tsars of Russia were crowned. The surprise is music. The base of the egg contains a gold music box that plays two cherubim chants, traditional Easter hymns can be played when a clockwork mechanism is wound up by a gold key. One of the hymns is the &quot;Izhe Khveruviny,&quot; a favorite hymn of Nicholas II.
