Judging by the Tsar Cannon's caliber of 890 mm, it was given its name as the world’s biggest cannon. The gun's tube's weight is about 40 ton, its length is 5,34 m. The cannon's surface is adorned with the cast figured friezes, vegetation ornament, memorial inscriptions and an equestrian image of Tsar Feodor Ioannovich. In 1835, the Tsar Cannon was fixed on the carriage specially cast for it at the Berdt’s factory in St. Petersburg. Four hollow decorative cannonballs were made at the same time.
The Tsar Cannon has never shot. Mostly of symbolic impact, it was never used in a war.
Initially, the Tsar Cannon was fixed on Red Square near the Spasskiye Gate. In 1706, it was moved into the Kremlin, fixed at first in the Arsenal’s inner yard and than at the main gate (with another cannon). In 1835, the two cannons were staged on the new bases, specially cast on the project of A. Bryullov. In 1843, the Tsar Cannon and other old Russian cannons were placed in front of the Armoury Chamber’s old building in the opposite of the Arsenal. The captured cannons were left by the Arsenal.
In 1960, when the Palace of Congresses (now it is named the Kremlin's State Palace) was under construction, the building of the Armoury Chamber (architect I. Yegotov) was dismantled. The old cannons were transferred to the Arsenal’s building.
Later the Tsar Cannon was fixed on its present-day place. In 1970s the Tsar Cannon, its base and cannonballs were renovated.
