The collection of artillery pieces of the Moscow Kremlin Museums, numbering about 800 items, is one of the largest of its kind in Russia. It was initiated by Peter I, who had a plan to erect a storehouse for “various armament and military trophies”. With regard to the number of artillery pieces, the museum occupies the second place just after the Artillery Museum in Saint Petersburg. Today, the museum collection of cannons dating back to the 16th-19th centuries is placed along the southern and eastern façades of the Arsenal building and at Ivanovskaya Square. Except for several arms kept in the museum funds, almost all the rich artillery collection is exhibited before the public.
