India

This massive and large Fort was built in 1726 and holds great appeal & Love for military lovers. Flanked towering gateways and watchtowers, it contains the world's largest cannon on wheels. The cannon has never been fired though, and neither has the fort been captured. As a result the fort has remained intact over its long life, and is very well preserved. In fact, it's one of the best-preserved military structures of medieval India. Jaigarh doesn't have the delicate interiors of Amber Fort, and therefore appears as a real fortress. Climb the Diwa Burj watchtower to get an excellent view over the plains.
