The Tsar Bell, also known as the Tsarsky Kolokol, Tsar Kolokol III, or Royal Bell, is a 6.14-metre tall, 6.6-metre diameter bell on display on the grounds of the Moscow Kremlin. The bell was commissioned by Empress Anna Ivanovna, niece of Peter the Great.
It has never been in working order, suspended, or rung.
The present bell is sometimes referred to as Kolokol III, because it is the third generation.
