Behind the displaySourced
Those cannonballs are decorations
Moscow’s bronze Tsar Cannon was cast in 1586. The large iron balls displayed in front of it were made in 1834 as decorations. They are too large to serve as its ammunition.
Standing beside a weapon does not make an object its working accessory.
