The Tsar Bell, also known as the Tsarsky Kolokol, Tsar Kolokol III, or Royal Bell. It is on display on the grounds of the Moscow Kremlin. The bell was commissioned by Empress Anna Ivanovna, niece of Peter the Great. The bell is decorated with relief images of baroque angels, plants, oval medallions with saints, and nearly life-size images of Empress Anna and Tsar Alexey, who was reigning at the time the previous Tsar Bell was cast.

The Tsar Bell is located between the Ivan the Great Bell Tower and the Kremlin Wall. Made of bronze, the bell cracked during a fire after being completed and has never been rung. The bell is the largest bell in the world, weighing 201,924 kilograms (445,166 lb), with a height of 6.14 metres (20.1 ft) and diameter of 6.6 metres (22 ft), and thickness of up to 61 centimetres (24 in). The broken piece weighs 11,500 kilograms (25,400 lb).
