The Jantar Mantar, Jaipur is a collection of 19 astronomical instruments built by the Rajput king Sawai Jai Singh II, the founder of Jaipur, Rajasthan. The monument was completed in 1734. It features the world's largest stone sundial, and is a UNESCO World Heritage site. It is near City Palace and Hawa Mahal. The instruments allow the observation of astronomical positions with the naked eye. The observatory is an example of the Ptolemaic positional astronomy which was shared by many civilizations.The monument features instruments operating in each of the three main classical celestial coordinate systems: the horizon-zenith local system, the equatorial system, and the ecliptic system. The Kanmala Yantraprakara is one that works in two systems and allows transformation of the coordinates directly from one system to the other. It has the biggest sundial in the world. The monument was damaged in the 19th century. Early restoration work was undertaken under the supervision of Major Arthur Garrett, a keen amateur astronomer, during his appointment as Assistant State Engineer for the Jaipur District.

Kingdom of Amber
Kingdom of Amber

The Kingdom of Amber, also known as Kingdom of Dhoondar and Jaipur State, was located in the Rajputana region of India and was ruled by the Kachhwaha clan. It was established by Dulha Rai, possibly the last ruler of the Kachchhapaghata dynasty of Gwalior who migrated to Dausa and started his kingdom there with the support of Chahamanas of Shakambhari in the 11th century. Mostly through 12th to 15th century, the kingdom faced stagnation sources are scarce. Under Chandrasen, it became a Sisodia vassal and fought in the Battle of Khanwa under Prithviraj Kachhwaha. Under Bharmal, the kingdom heavily aligned with the Mughals and he even married his daughter to Akbar. His son and grandson Bhagwant Das and Raja Man Singh were leading generals in Akbar's army and helped him in expanding the empire. Mirza Raja Jai Singh served under Shah Jahan and became a distinguished general. He fell out of Aurangzeb's favor when he was suspected of helping Shivaji escape from Mughal captivity in 1664. Sawai Jai Singh II became the ruler during the decline of the Mughal empire. He successfully rebelled against the Mughals in 1708 to regain his confiscated kingdom. After Jai Singh's death, the kingdom was drained of its resources during the civil war amongst his sons Ishwari and Madho Singh and the Marathas caused the Kingdom to fall into economic downturn. It became a princely state under the East India Company rule after signing a treaty creating a subsidiary alliance with the Company in 1818, after the Third Anglo-Maratha War. It acceded to independent India in 1947 and was integrated into India by 1949. Upon integration, the ruler was granted a pension (privy purse), certain privileges, and the use of the title Maharaja of Jaipur by the Government of India. However, the pension, privileges, and the use of the title were ended in 1971 by the 26th Amendment to the Constitution of India.

Hawa Mahal
Hawa Mahal

The Hawa Mahal is a palace in the city of Jaipur, India. Built from red and pink sandstone, it is on the edge of the City Palace, Jaipur, and extends to the Zenana, or women's chambers. The structure was built in 1799 by the Maharaja Sawai Pratap Singh, grandson of Maharaja Sawai Jai Singh, the founder of the city of Jaipur, India. He was so inspired by the unique structure of Khetri Mahal that he built this grand and historical palace. It was designed by Lal Chand Ustad. Its five-floor exterior is akin to a honeycomb with its 953 small windows called Jharokhas decorated with intricate latticework. The original intent of the lattice design was to allow royal ladies to observe everyday life and festivals celebrated in the street below without being seen. This architectural feature also allowed cool air from the Venturi effect to pass through, thus making the whole area more pleasant during the high temperatures in summer. Many people see the Hawa Mahal from the street view and think it is the front of the palace, but it is the back.In 2006, renovation works on the Mahal were undertaken, after a gap of 50 years, to give a facelift to the monument at an estimated cost of Rs 4.568 million. The corporate sector lent a hand to preserve the historical monuments of Jaipur and the Unit Trust of India has adopted Hawa Mahal to maintain it. The palace is an extended part of a huge complex. The stone-carved screens, small casements, and arched roofs are some of the features of this popular tourist spot. The monument also has delicately modelled hanging cornices.
