Jantar Mantar is located at Jaipur in the beautiful state of Rajasthan. It is famous for having numerous archaeological astronomical instruments. It was built by Sawai Jai Singh, who was a Rajput King. He also had a great interest in architecture, mathematics and astronomy. Between 1727 and 1734, he built five astronomical observatories at five places namely Delhi, Mathura, Benares, Ujjain and Jaipur. Out of these five, only the observatory at Jaipur is still operational and the rest of them are in ruins. Jantar Mantar at Jaipur was designed after the construction of the Jantar Mantar in the Mughal capital of Delhi. The word Jantar Mantar is derived from ‘Jantar’ which means device and ‘Mantar’ means calculation or formula thus, Jantar Mantar basically means formulating or calculative instrument. This tower also has a lot of religious importance as the ancient astrologers were also known as masters of Jyotisa. The tower consists of fourteen mathematical instruments which measures time, tracks the location of stars, calculates the celestial distances, forecasting eclipses and associated chronicles.
Today, Jantar Mantar is counted among the famous tourist destinations and is considered as the biggest and largest tourist destinations in the World Heritage List. It is an eye-catching and magnificent structure of Jaipur. In addition, it also has numerous eye-catching and exquisite places in close vicinity to be visited which include the City palace, Galta Monkey Temple and Jaigarh fort.

Each instrument present in the Jantar Mantar is a fixed and ‘focused’ tool. The biggest instrument present here is known as Samrat Yantra. It is the world’s largest sundial standing 90 feet tall. Its shadow has been plotted carefully which tells the time of the day. Its front portion is angled at 27⁰ towards the latitude of Jaipur. The Hindu Chhatri or the small dome is fixed on the top which is used as a platform for indicating the eclipse and the arriving monsoon. These instruments are huge structures, made up of marbles and the local stones and carries extensive scales on the inner marble linings.
