Jantar Mantar is a unique astronomical observatory located in the heart of New Delhi, India. It was built in the early 18th century by Maharaja Jai Singh II of Jaipur, who was a renowned astronomer and mathematician. The name "Jantar Mantar" is derived from the Sanskrit words "yantra" and "mantra", which mean "instrument" and "formula" respectively.
The observatory consists of a collection of 13 architectural instruments, which were used to measure time, track celestial movements, and predict eclipses. These instruments are made of stone, marble, and brass, and are arranged in a geometric pattern on a large open ground. The most impressive of these instruments is the Samrat Yantra, which is a massive sundial that can accurately measure time to within two seconds.
Other notable instruments at Jantar Mantar include the Jai Prakash Yantra, which is a pair of hemispherical structures used to measure the altitude and azimuth of celestial bodies, and the Misra Yantra, which is a set of five instruments used to measure the declination and right ascension of stars.
Jantar Mantar is not only a remarkable feat of engineering and astronomy, but also a testament to the scientific and intellectual achievements of ancient India. It is a popular tourist attraction and a must-visit destination for anyone interested in astronomy, history, or architecture.
