Following is a list of the heaviest bells known to have been cast, and the period of time during which they held that title. Heaviest functioning bell in the world The title of heaviest functioning bell in the world has been held chronologically by: The Great Bell of Dhammazedi At approximately 300 tons, the Great Bell of Dhammazedi is the largest bell to have existed in recorded history. Cast in 1484 by King Dhammazedi of Mon, this bell was located at the Shwedagon Pagoda in Rangoon, Burma (now Yangon, Myanmar). The bell was said to be twelve cubits (6.276 m) high and eight cubits (4.184 m) wide. Click here to see a drawing of the bell as it appeared while still at the Shwedagon Pagoda. The Great Bell of Dhammazedi remained at the Shwedagon Pagoda as the heaviest functioning bell in the world until 1602. That year, Portuguese warlord and mercenary Philip de Brito removed it and attempted to carry it by a specially constructed raft down the Yangon River to his stronghold of Thanlyin (later known as Syriam). However, the ship carrying the bell sank at the confluence of the Yangon and Bago rivers. The Dhammazedi Bell remains buried to this day at that location, possibly well-preserved, beneath some of sediment. Numerous attempts have been made to locate and recover the bell, thus far without success. So while the Great Bell of Dhammazedi might indeed be the heaviest bell in the world, it must be disqualified from consideration as such, until it has been recovered and restored to a functional status. The Chion-in Temple Bell Cast in 1633, the 74-ton Chion-in Temple Bell, located in Kyoto, Japan, held the title of heaviest functioning bell in the world until 1810. From March 1839 until March 1896, the Mingun Bell was not functional due to the fact that it was not hanging freely from its shackles. During this period, the Chion-in Temple Bell regained its former title. The Mingun Bell Cast in 1808, the 90-ton Mingun Bell in Mingun, Sagaing Division, Burma became the heaviest functioning bell in the world from its suspension in 1810 until 23 March 1839. On that date, it was knocked off its supports by a large earthquake. Click here to see a photograph of the Mingun Bell as it appeared in the late 1800s.
