Geography

It provides an excellent of view of Aravalli hills and the Amer Fort down below.The fort is away from Jaipur city.

It can also be approached from the Amer Fort over a short climb along a steep hill track, arriving at the Awami Gate near the fort museum.
History
Amer was known in the ancient and medieval period as Dhundhar. What is known in the present day as Jaigarh Fort, which was actually the main defensive structure rather than the palace itself. The two structures are interconnected by a series of encompassing fortifications and ruled by the Kachwahas from the 10th century onwards. The history of Amer and Jaigarh is indelibly linked to these rulers, as they founded their empire at Amer.Cannon foundry
During the reign of the Mughal Emperor Shah Jahan, Jaigarh Fort, which is located 150 miles south-west of Delhi, became one of the world's most efficient cannon foundries mainly due to the abundance of iron ore mines in the vicinity of the fort. The cannon foundry Jaigarh Fort had a massive wind tunnel that sucked air from the high mountains into its furnace creating temperatures as high as, the heated air would melt the metal. The molten metal would fill a reservoir chamber and pass into a cannon mold in the casting pit. Most of those cannons were massive, mostly 16 ft long and had to be prepared within a single day. The Rajput also built a large ingenious mechanical device that had a precision gear system driven by four pairs of oxen, the device was used for hollowing out the cannon barrels. When the Mughal war of succession broke out in 1658 Dara Shikoh secured the cannon outpost of Jaigarh Fort until he was defeated and executed by his younger brother Aurangzeb. Later however, the Mughal Emperor Muhammad Shah appointed Jai Singh II as the official Mughal quiladar of Jaigarh Fort according to a Firman, ultimately Jai Singh II is known to have molded the great Jaivana Cannon by utilizing the important foundry and devices inside Jaigarh Fort.Description
The fort is highly fortified with thick walls of red sandstone and is spread over a layout plan with a length of and a width of ; it has an impressive square garden within it. Ramparts in each corner are sloping and provide access to the upper level structures. The palaces have court rooms and halls with screened windows. A central watch tower on a raised ground provides excellent vistas of the surrounding landscape. The Aram Mandir and the garden within its courtyard, on the northern side of the fort complex, has a triple arched entrance "The Awani Darwaza" which was refurbished in recent times to get fine views of the Sagar Lake ; water from this lake used to be transported to the fort in pouches loaded on elephant backs and also by humans carrying water pots. The triple arch gateway with fortification walls above it is painted red and yellow. It is oriented in an east–west direction and faces west. The architectural features are of Indo-Persian style with cyclopean walls built with dressed stone and plastered with lime mortar. There are two temples within the fort precincts, one is the Ram Harihar temple of the 10th century and the other one is the Kal Bhairav temple of 12th century vintage.at Jaigarh Fort
The water supply facilities in the fort was met by creating water harvesting structures in the vicinity in the Aravalli catchment and conveying water through a canal on the west side of the fort over a distance to be stored in three underground tanks below the central courtyard. The largest tank had a capacity of 6 million gallons of water. There were completely false rumors, that a treasure belonging to the Kachwaha rulers of Amer had been stacked in the fort precincts, that led to a totally unsuccessful search. The search had been ordered during the Emergency declared by the Indian Prime Minister Indira Gandhi during 1975–1977. A futile search was also launched, in 1977, of all the buildings in the fort, by the Income Tax department, using metal detectors. There was also a Parliament Question on this issue where a question was posed whether a "Search for treasure carried out from 10 June 1976 till November 1976 by the Income Tax Authorities at Jaigarh Fort on the Jaipur Delhi Road was closed to ordinary traffic for one or two days so as to make way for military trucks carrying treasures to the residence of the then Prime Minister, Smt. Indira Gandhi?". However, the search carried out for treasures by an Army unit at Jaigarh Fort, after a three-month search had found no treasures. It was then conjectured that Sawai Jai Singh probably used the treasure to build the city of Jaipur.

Jaigarh Fort was a centre of artillery production for the Rajputs. It is now home to the Jaivana – at the time of its manufacture in 1720, it was the world's largest cannon on wheels of the Early Modern Era. The foundry where it was manufactured is also located here. A plaque at the entrance to the enclosure where the Jaivan Cannon is displayed gives relevant information on the history of the Cannon, its size and use. This cannon was never used in any battle as the Rajput rulers of Amer had friendly relations with the Mughals. This testifies to well-preserved features of fort.
