This burj, built of earthwork is of strategic importance for the Jat rulers of Bharatpur due to location of the famous cannon over it, which perhaps played an important role in the victory of the rulers. The cannon is 6 m long with frontal diameter of 0.68 m. The perimeter on rear side is 2.67 m. The diameter of the slot is 16.5 cm. The cannon is placed over two stone shafts in east-north-east west-southwest alignment. The cannon bears engravings of rows of continuous arches, floral designs, a swastik design and figure probably of a dog in dotted lines. The cannon is possibly made of wrought iron. The date is assignable to eighteenth century A.D.
