The Kremlin Armoury (Russian: Оружейная палата) is one of the oldest museums of Moscow, established in 1808 and located in the Moscow Kremlin. The Kremlin Armoury originated as the royal arsenal in 1508. Until the transfer of the court to St Petersburg, the Armoury was in charge of producing, purchasing and storing weapons, jewelry and various household articles of the tsars. The finest Muscovite gunsmiths (the Vyatkin brothers), jewelers (Gavrila Ovdokimov), and painters (Simon Ushakov) used to work there. Alexander I of Russia nominated the Armoury as the first public museum in Moscow in 1806, but the collections were not opened to the public until seven years later. The Kremlin Armoury is currently home to the Russian Diamond Fund. It boasts unique collections of the Russian, Western European and Eastern applied arts spanning the period from the 5th to the 20th centuries. Some of the highlights include the Imperial Crown of Russia by jeweller Jérémie Pauzié, Monomakh's Cap, the ivory throne of Ivan the Terrible, and other regal thrones and regalia.
