Spanning three kilometres in length and one kilometre in width across the Aravalli Ranges, Jaigarh Fort overlooks and is connected by underground tunnels to Amber Fort. Views from the fort encompass both Amber and Maota Lake. Within its tremendous red stone walls lie beautiful palaces, gardens, courtyards and temples. Due to the abundance of iron ore in the vicinity, shortly after it was completed in 1726, Jaigarh became a prolific cannon foundry.
In the late 1970s, a rumour was started that hidden within Jaigarh was a missing treasure belonging to the Kachwaha rulers of Amer. The rumour gained such impetus that the Income Tax Department of India, under the directive of the Prime Minister Indira Gandhi, even conducted a two day search for the treasure using metal detectors. But to no avail. Nowadays, the most significant treasure here is the cannon foundry’s massive and highly ornate, fifty tonne Jaivana cannon and matching fifty kilogramme cannon ball.
