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. In 1640 and 1683, they opened the iconography and pictorial studios, where the lessons on painting and handicrafts could be given. In 1700, the Armoury was enriched with the treasures of the Golden and Silver chambers of the Russian tsars.
