Narivalaya Dakshin Gola, used to determine whether celestial bodies are in the Northern or Southern hemisphere, and to tell the time, at Jantar Mantar, a monument completed in 1734 built by Maharaja Sawai Jai Singh, founder of Jaipur, featuring 19 architectural astronomical instruments, in Jaipur, Rajasthan, India. The instruments allow the observation of astronomical positions with the naked eye. They measure time, predict eclipses, track the location of major stars and ascertain the declinations of planets.
