Jantar Mantar Observatory
‘Jantar Mantar’ in Jaipur, is another most famous tourist attraction of the city. Hundreds of historians, astronomers and curious travellers visit this place to get a picture of the astronomical skills of an Indian king during an era when these scientific concepts were very new to the Indian society. Holding the status of UNESCO World Heritage site, the monument was built in 1738 by Maharaja Sawai Jai Singh, who is believed to have a keen interest in astronomy. The monument houses a unique and impressive collection of astronomical instruments made of stone and brass based on the astronomical design principles of Hindu texts of astrology and modern science; some of the instruments are largest ever built in their particular categories. Through these instruments, which are fixed on the ground, you can observe various astronomical positions with the naked eye. The ‘Samrat Yantra’ in the observatory is the world’s largest sundial and needs a special mention. Boasting of the brilliant architectural, astronomical and cosmological concepts of Sawai Jai Singh, the observatory is indeed an astronomical heritage of the city.
