The Czar Bell (1733-1735) at the Kremlin in Moscow, Russia

The Czar Bell (Czar-kolokol), also known as the Czarsky Kolokol, Czar Kolokol III, or Royal Bell, is a 6.14-meter (20.1 ft) tall, 6.6-meter (22 ft) diameter bell on display on the grounds of the Moscow Kremlin. The bell was commissioned by Empress Anna Ivanovna, niece of Peter the Great. The present bell is sometimes referred to as Kolokol III (Bell III), because it is the third generation. The Czar Bell is located between the Ivan the Great Bell Tower and the Kremlin Wall. Made of bronze, the bell was broken during metal casting and has never been rung. The bell is currently the largest bell in the world, weighing 201,924 kilograms (445,166 lb), with a height of 6.14 meters (20.1 ft) and diameter of 6.6 meters (22 ft), and thickness of up to 61 centimeters (24 in). The broken piece weighs 11,500 kilograms (25,400 lb). The bell is decorated with relief images of baroque angels, plants, oval medallions with saints, and nearly life-size images of Empress Anna and Czar Alexey, who was reigning at the time the previous Czar Bell was cast.
