Wander around a bit and one can walk the ramparts and peer down the loopholes for guns and boiling oil, or check out the wide water channels. These are part of a very efficient system for rainwater harvesting, bringing in water from across the hills and into Jaigarh's 3 underground water tanks. The largest of the tanks stored 6,000,000 gallons of water enough to feed 10000 troops for 2 years. It is also believed that a huge treasure was buried under the tank until the government seized it during emergency in the 1970s. A case is till in court, but nothing has surfaced. The fort is now privately owned and the museums offer a brief but grand look in to the mighty power of the Rajput dynastys military power.
