Jantar Mantar

The Jantar Mantar situated at Sansad Marg between Connaught Place and
Rashtrapati Bhavan New Delhi, Jantar Mantar is one of the five
observatories built by Maharaja Sawai Jai Singh II, the ruler and
founder of Jaipur, in India. Smaller than the one at Jaipur, it is
still astonishing because of its capability to make accurate
calculations of many astronomical movements. Constructed in 1724, the
giant abstract masonry instruments of Jantar Mantar are the evident of
the technological genius of the times in the field of astronomy. Jai
Singh was a keen astronomer and a noble in the Mughal court.
Vast red and white sloping stone structures hover over palm trees and

He was dissatisfied by the brass and metal astronomical instruments
and decided to correct and update the astronomical records with more
accurate instruments. He built five Jantar Mantars in India,

at an angle of 27 degrees. The other yantras in this observatory are
used to observe the various stars and planets. The Mishra Yantra helps
to determine the longest and shortest days in the year. In December,
one pillar overshadows the other and in June, it does not cast any
shadow at all.

When compared to others, this observatory is the largest and the best
preserved today. But, after its erection in 1724, it remained
functional only for seven years. Observations made each day were noted
down and later a chart called Zij Muhammad Shahi was prepared. This
was then dedicated to the reigning monarch. Many experts in this field
are of the view that these observatories fell into disuse, because of
lack of thought on the part of the king. The original name Yantra
(instrument) mantra (formula) has been corrupted to Jantar Mantar.

Jantar Mantar is one of the top attractions of Delhi. It draws a
stream of visitors all round the year. With hotels of Delhi you can
have the glimpse of the astronomical advancement India had made in
ancient period.

The famous 18th century astronomer king and the founder of the Pink
city of Jaipur, Sawai Jai Singh, built the first of his five
astronomical observatories across India.

The observatories are known as Jantar Mantar which derives it name
from the corruptions of the words ‘yantra’ (instrument) ‘mantra’
(formula) over the period.
