The Nine Holy Cannons (Cửu Vị Thần Công) are a set of nine bronze cannons placed in front of the Imperial Citadel of Hue, Vietnam. Cast in 1803 under Emperor Gia Long, they were intended as both defensive weapons and symbolic guardians of the realm. Each cannon is named after one of the four seasons or the five elements (metal, wood, water, fire, earth), reflecting Confucian cosmology. The cannons are arranged symmetrically on stone platforms, their muzzles pointing outward. Visitors can walk among them, admiring the intricate engravings and the sheer scale of these historic artifacts. Though never used in battle, they remain a powerful emblem of the Nguyen dynasty's authority and craftsmanship.
