[1] Per the Guinness Book of Records it is the largest bombard by caliber in the world,[2] and it is a major tourist attraction in the ensemble of the Moscow Kremlin.

Above the front right bracket the message "The grace of God, Tsar and Great Duke Fyodor Ivanovich, Autocrat of All Russia" was cast.

There were two more labels cast at the top of the barrel, to the right is "The decree of the faithful and Christ-king and the Grand Duke Fyodor Ivanovich, Sovereign Autocrat of all Great Russia with his pious and god-blessed queen, Grand Princess Irina"; While to the one to the left is "Cast in the city of Moscow in the summer of year 7904 (c. 1585 in Gregorian calendar), in his third summer state, by Andrey Chokov."

The spherical cast-iron projectiles located in front of the Tsar Cannon—each of which weighs approximately one ton—were produced in 1834 as a decoration, and are too large to have been used in the cannon.

The carriages and the cannon itself were richly decorated in 1835 at the St. Petersburg plant of Berd, with designs by architect A. P. Bryullov and drawings engineer P. Ya.

It is known to have been mounted on a special frame with a fixed inclination angle in the Red Square near the Place of Skulls in order to protect the eastern approaches to the Kremlin, indicating that it originally did have a practical application.

[5] For a long time, there was a common theory that the Tsar Cannon was created only to impress foreigners of Russia's military powers.

Even if we assume that the barrel would fire grapeshot, a massive amount of propellant would be needed to push the two-ton shot, making it impossible for the cannon to be transported from one position to another.

It was thoroughly studied by specialists in the Artillery Academy at that time and gunpowder residue was found, indicating that the cannon had been fired at least once, hinged and dug into the ground.

The cannon, nicknamed the "Perm Giant", was made in 1868, by the order of the Ministry of Marine to the Motovilikha manufacturing plant (which is PAO "Motovilikha Plants" today, manufacturing weapon systems such as cannons, mortars, howitzers, self-propelled artillery, "Grad", "Uragan" and "Smerch" rocket systems).

Yes, and there was no one, except on Sundays, when the plant was silent as tiny spiders float on the river and boats carry people from the factory to Zakamskaya Pohulyanka.

There was no one, and no guns behind the Dalyu on the other side, only the smoke from the volleys indicated where the cannons were firing from… The river roared, shaking the air, and the mood of war was all over.

"[8]A model of the Perm Tsar Cannon in full size was put before the Russian Pavilion at the 1873 World Exhibition in Vienna.

The Perm cannon was to take its place in Kronstadt at Fort Constantine (Russia), where a special carriage was already installed to ensure all-around coverage, and to protect St. Petersburg from the sea.

This is due to the fact that the engineer-inventor Pavel Matveyevich Obukhov of Zlatoust has developed the technology to produce high-strength steel cannons.

Today, the Perm Tsar Cannon is held on exhibition in the open museum of military equipment belonging to PAO "Motovilikha Plants".
