''Topekhana'' was the [[Nawabs of Bengal|Nawab's]] Artillery Park and the entrance gate of the old capital of [[Bengal]], [[Bihar]] and [[Orissa, India|Orissa]], the city of [[Jahangir Nagar]]. It is protected on the east by the ''Gobra Nala'', locally known as the ''Katra Jheel''. Here, the Jahan Kosha Cannon is laid to rest. Before being placed at its current location, it rested on a carriage with wheels and was surrounded by the roots of a [[Sacred fig|Peepal tree]].<ref>http://murshidabad.net/history/places-topic-places-zone-three.htm#katra-mosque</ref> The growth of the tree roots gradually lifted the gun four feet above the ground. The wheels of the gun carriage have disappeared, but the iron-work of the carriage and the trunions are still visible. The cannon is made of ''[[ashtadhatu]]'' or 8 metals, namely silver, gold, lead, copper, zinc, tin, iron and mercury. [[File:Jahan Kosha Cannon.jpg|thumb|An old photo of the cannon, when it was lifted four feet by the roots of a [[Peepal tree]].]] The cannon is more than 7 tons in weight. It is 17 feet and 6 inches in length and 3 feet in width. It has a girth of 5 feet at the touch hole end. The circumference of its mouth is more than one foot. The radius of the touch hole is one and a half inches. In order to fire this cannon once, 17 kilograms of gunpowder was needed. The bore is approximately 6 inches. [[File:Jahan Kosha Cannon - Murshidabad.jpg|thumb|left|The other side of the cannon.]] [[File:Description of Jahan Kosa Gun for tourists.jpg|thumb|right|Information placard about Jahan Kosha Cannon in the campus]] The cannon was made in 1637 by Janardan Karmakar, a blacksmith and gunsmith, under the instructions of Daroga Shere Mohammad and under the supervision of Hara Ballav Das. The cannon was made in [[Dacca]], when [[Shah Jahan]] was the [[Mughal Empire|Mughal]] emperor, at the instance of [[Islam Khan II|Islam Khan]], who was the [[Subedar]] of [[Bengal]]. This is confirmed by an inscription engraved on it. However, the cannon has several other names like the "''Great Gun''", the "''Destroyer of the world''", the "''Conqueror of the universe''", the "''World Subduer''" and so on. The cannon is maintained by the [[Archaeological Survey of India]]. ==References== {{reflist}} ==External links== {{commons category}} * {{cite web|url=http://murshidabad.net/history/places-topic-places-zone-three.htm#jahan-kosha|title=The official website}} {{Tourist attractions in Murshidabad}} [[Category:Tourist attractions in Murshidabad]] [[Category:Large-calibre artillery]] [[Category:Artillery of India]] [[Category:Individual cannons]] [[Category:History of Dhaka]] [[Category:1637 establishments in Asia]]'
