The Moscow Kremlin Egg is by far the largest of the Carl Faberge eggs and was inspired by the architecture of the Moscow Uspenski Cathedral, where all the Russian Tsars were crowned.

The egg commemorates the return to Moscow of the royal couple Nicholas II and Alexandra Fyodorovna in 1903. They had tended to avoid the historical capital due to its ill-omened association with a riot during Nicholas’s coronation, where hundreds of Moscovites were crushed to death. The egg itself was supposed to be presented in 1904 as engraved at the foot in white enamel on a round gold plate is the date. But the delivery was delayed because of the Russo-Japanese War (1904-1905). This was followed by the assassination in the Kremlin of Nicholas' favorite uncle and brother-in-law, Grand Duke Sergei Alexandrovich. So instead the egg was only presented for Easter, 1906. The egg was kept in the Alexandra Fyodorovna’s Mauve Sitting Room in the Alexander Palace.
