* NAHARGARH FORT -: Built mainly in 1734 by Maharaja Sawai Jai Singh, the king of Jaipur, the fort was constructed as a place of retreat on the summit of the ridge above the city. Walls extended over the surrounding hills, forming fortifications that connected this fort to Jaigarh, the fort above the old capital of Amber. Though the fort never came under attack during the course of its history, it did see some historical events, notably, the treaties with the Maratha forces who warred with Jaipur in the 18th century. During the Indian Mutiny of 1857, the Europeans of the region, including the British Resident's wife, were moved to Nahargarh fort by the king of Jaipur, Sawai Ram Singh, for their protection.
The fort was extended in 1868, during the reign of Sawai Ram Singh. In 1883-92, a range of palaces was built at Nahargarh by Dirgh Patel at a cost of nearly three and a half lakh rupees. The Madhavendra Bhawan, built by Sawai Madho Singh had suites for the queens of Jaipur and at the head was a suite for the king himself. The rooms are linked by corridors and still have some delicate frescoes. Nahargarh was also a hunting residence of the Maharajas.
Until April 1944, the Jaipur State government used for its official purposes solar time read from the Samrat Yantra in the Jantar Mantar Observatory, with a gun fired from Nahargarh Fort as the time signal.
Some scenes in the movies Rang De Basanti, Shuddh Desi Romance and Sonar Kella were shot at Nahargarh Fort.
* JAIGARH FORT -: The Jaigarh Fort, located on one of the peaks of the Aravalli range of hills is built about 400 m above the Amer Fort. It provides an excellent of view of Aravalli hills and the Amer Fort down below.
The fort is 10 kilometres (6.2 mi) away from Jaipur city. It stands on a short diversion from the Jaipur-Delhi Highway, which leads to the Jaivaan cannon at the Dungar Darwaza ('Darwaza' means "gate"), the same road leads to another important fort called the Nahargarh Fort. 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
* AMBER FORT -: Amer Fort or Amber Fort is a fort located in Amer, Rajasthan, India. Amer is a town with an area of 4 square kilometres (1.5 sq mi) located 11 kilometres (6.8 mi) from Jaipur, the capital of Rajasthan. The town of Amer and the Amber Fort were originally built by Raja Man Singh and additions were, later, made by Sawai Jai Singh. Located high on a hill, it is the principal tourist attraction in Jaipur. Amer Fort is known for its artistic style elements. With its large ramparts and series of gates and cobbled paths, the fort overlooks Maota Lake, which is the main source of water for the Amer Palace.
Amer Palace is great example of Rajput architecture. Some of its buildings and work have influence of Mughal architecture. Constructed of red sandstone and marble, the attractive, opulent palace is laid out on four levels, each with a courtyard. It consists of the Diwan-e-Aam, or "Hall of Public Audience", the Diwan-e-Khas, or "Hall of Private Audience", the Sheesh Mahal (mirror palace), or Jai Mandir, and the Sukh Niwas where a cool climate is artificially created by winds that blow over a water cascade within the palace. Hence, the Amer Fort is also popularly known as the Amer Palace. The palace was the residence of the Rajput Maharajas and their families. At the entrance to the palace near the fort's Ganesh Gate, there is a temple dedicated to Shila Devi, a Goddess of the Chaitanya cult, which was given to Raja Man Singh when he defeated the Raja of Jessore, Bengal in 1604. (Jessore is now in Bangladesh). Raja Man Singh had 12 queens so he made 12 rooms, one for each Queen. Each room had a staircase connected to the King’s room but the Queens were not to go upstairs. Raja Jai Singh had only one queen so he built one room equal to three old queen’s rooms.
This palace, along with Jaigarh Fort, is located immediately above on the Cheel ka Teela (Hill of Eagles) of the same Aravalli range of hills. The palace and Jaigarh Fort are considered one complex, as the two are connected by a subterranean passage. This passage was meant as an escape route in times of war to enable the royal family members and others in the Amer Fort to shift to the more redoubtable Jaigarh Fort. Annual tourist visitation to the Amer Palace was reported by the Superintendent of the Department of Archaeology and Museums as 5000 visitors a day, with 1.4 million visitors during 2007. At the 37th session of the World Heritage Committee held in Phnom Penh, Cambodia, in 2013, Amer Fort, along with five other forts of Rajasthan, was declared a UNESCO World Heritage Site as part of the group Hill Forts of Rajasthan
* JALMAHAL -: The Jal Mahal palace is an architectural showcase of the Rajput style of architecture (common in Rajasthan) on a grand scale. The building has a picturesque view of Man Sagar Lake, but owing to its seclusion from land is equally the focus of a viewpoint from the Man Sagar Dam on the eastern side of the lake in front of the backdrop of the surrounding Nahargarh ("tiger-abode") hills. The palace, built in red sandstone, is a five-storied building, of which four floors remain underwater when the lake is full and the top floor is exposed. One rectangular Chhatri on the roof is of the Bengal type. The chhatris on the four corners are octagonal. The palace had suffered subsidence in the past and also partial seepage (plaster work and wall damage equivalent to rising damp) because of water logging, which have been repaired under a restoration project of the Government of Rajasthan.
The hills surrounding the lake area, towards the north east of Jaipur, have quartzite rock formations (with a thin layer of soil cover), which is part of the Aravalli hills range. Rock exposures on the surface in some parts of the project area have also been used for constructing buildings. From the northeast, the Kanak Vrindavan valley, where a temple complex sits, the hills slope gently towards the lake edge. Within the lake area, the ground area is made up of a thick mantle of soil, blown sand, and alluvium. Forest denudation, particularly in the hilly areas, has caused soil erosion, compounded by wind and water action. As a result, silt built up in the lake incrementally raises the lake bed. On the terrace of the palace, a garden was built with arched passages. At each corner of this palace semi-octagonal towers were built with an elegant cupola.
The restoration works of the early 2000s were not satisfactory and an expert in the field of similar architectural restoration works of Rajasthan palaces examined the designs that could decipher the originally existing designs on the walls, after removing the recent plasterwork. Based on this finding, restoration works were re-done with traditional materials for plastering – the plaster consists of partly organic material: a mortar mix of lime, sand and surkhi mixed with jaggery, guggal and methi powder. It was also noticed that there was hardly any water seepage, except for a little dampness, on the floors below the water level. But the original garden, which existed on the terrace had been lost. Now, a new terrace is being created based on a similar roof garden of the Amer Palace. The building is located near the shoreline of a lake with a maximum depth of 15 ft. As the four stories of the building are built under the water, this means it would be structured on the bottom of the lake.
