The Kremlin Arsenal (Russian: Арсенал Московского Кремля) is a former armory built within the grounds of the Moscow Kremlin in Russia. Initially constructed in 1736, it has been rebuilt several times. It remains in military use to date, unlike the Kremlin Armoury, another arsenal within the walls of the Moscow Kremlin, which is now a museum. The building is off-limits to tourists.
An arsenal is a place where arms and ammunition are made, maintained and repaired, stored, or issued, in any combination, whether privately or publicly owned. Arsenal and armoury (British English) or armory (American English) are mostly regarded as synonyms, although subtle differences in usage exist.
A sub-armory is a place of temporary storage or carrying of weapons and ammunition, such as any temporary post or patrol vehicle that is only operational in certain times of the day.
