The exposed cannon was discovered in the village of Grinăuți-Moldova, Ocnița district, it dates from the second half of the 15th century. From a typological point of view, in the central-eastern European space, the cannon from Grinăuți-Moldova is a unique piece.

It is a short-barreled mortar-type artillery piece that fits perfectly into the line of bombards in Europe used in the second half of the 15th century - the beginning of the 16th century.

The cannon was used to launch projectiles (bullets) at the enemy behind fortifications or natural obstacles. The projectiles were loaded through the mouth of the barrel. The firing angle was over 45 degrees, and the trajectory of the projectile was curved with a range of up to 300-400 m. In Europe, these cannons were called mortars, and in Romanian space they were designated by the word piua, thanks to the shape of this object.

According to a legend from the village of Grinăuți-Moldova, in the "Red Bank" location, a military confrontation between Moldovans and Tatars would have taken place prior to the battle of Lipnic.
