Why to visit JANTAR MANTAR

The enormous observatory known as Jantar Mantar is situated in Parliament Street, south of Connaught Circle, in New Delhi. It was constructed to aid and advance the field of known studies of time and space. It is one of five observatories of its kind that were erected by Maharaja Jai Singh in 1724 and is situated at Jaipur, Ujjain, Varanasi, and Mathura.

The 13 architectural astronomy devices that make up Delhi's Jantar Mantar can be used to create astronomical tables and forecast the movements and times of the sun, moon, and planets.

How does the Jantar Mantar works? 

  • The preparation of astronomical instruments was the main goal behind the construction of this enormous observatory.
  • These were then used to monitor the movement and changes of the sun, the moon, and the several planets that make up our solar system in order to track the local time zones.
  • As a result, a highly valuable observatory from antiquity never fails to astound astronomers and academics who are heavily influenced by technology.

Samrat Yantra, Jayaprakash, and Misra Yantra are the names of the three instruments:

  • The Samrat Yantra is a huge triangle that is 114 feet long, 10 feet thick, and 70 feet high. It is a sundial designed to determine the time of day with a half-second precision.
  • The Jayaprakash Yantra is made up of hemispheres that have been hollowed out and have markings on their concave surfaces. A star's location can be matched up with different markings or the age of a window from the inside.
  • The longest and shortest days of the year can be calculated using the Misra Yantra. No matter how far away from Delhi a city or place is, it also shows the precise time of noon there.
  • As a result, Delhi's Jantar Mantar brings the three distinct dimensions of belief, the cosmos, and society close at hand. It combines astronomical knowledge with cosmological ideas that originated in the court of a learned ruler.

Entrance fee and timings at Jantar Mantar:

  • The Jantar Mantar is open from six in the morning till six in the evening. Every day of the week, it is open. 
  • For Indian visitors to the Jantar Mantar, the entrance fee is Rs. 15, while the cost for foreign visitors is Rs. 200 per person.
