Jaigarh Fort was built between the 15th and the 18th century and is located on one of the peaks of the Aravali range of hills. It provides an excellent view of the Aravali hills and the Amber Fort down below. Jaigarh Fort stands amid rock-strewn, thorn-scrub covered hills, and its foreboding stone ramparts are visible from Jaipur, 15 km away. A steep road goes up to the main gate, the Dungar Darwaza. Jaigarh Fort is the most spectacular of the three-hilltop forts that overlook Jaipur. Jaigarh Fort is also known as the Fort of Victory. In Mughal times, the Jaipur region was a major weapon-producing center for the Mughal and Rajput rulers. Several of these weapons are on display in the fort's armory and museum. It is one of the few military structures of medieval India preserved almost intact; the fort contains palaces, a granary, a well-planned cannon foundry, several temples, a tall tower and giant mounted cannon-the Jai Ban, which is the largest cannon on wheels in the world. The armory display includes a collection of canons, many of which are exquisitely decorated and were used in the Mughal campaigns led by the, Rajput King, Raja Man Singh.
