Never conquered in battle, this was considered the strongest of the three forts in the area. It is best known as the site of the world’s largest cannon, the Jaivana, which was test-fired only once according to legend, despite using only the half the design amount of gunpowder, the cannonball flew 35 km! A better reason to visit the fort, though, are the scenic gardens at the other end and the spectacular views over the Amber Fort and the hills around.
