When we think of a King, we imagine a warrior, philanthropist, tyrant, or a great admirer of culture.
But, have you heard about a king who was an immense scholar of Astrology?

At the age of eleven, Sawai Jai Singh became King of Amber, and due to his analytical skills, display of bravery to rule the Kachhawa kingdom, Mughal king Aurangzeb gave him the honorary title of Sawai, meaning someone above average man in strength and intelligence.

The King Sawai Jai Singh of Amber (Presently Jaipur) was the one who had immense interest in Mathematics, Trigonometry, Architectures, and Astrology. His love for architecture is visible in his capital city of Jaipur. Pink city is also the first Indian city made under proper planning.

To excel in his love of Astrology, he built five observatories in India, the cities in which these observatories are New Delhi, Mathura, Ujjain, Varanasi, and Jaipur.

These Observatories have stone sundials that keep on predicting the accurate time of day, and the ancient day Astrology has been able to guide until some of the modern-day apparatus came into existence.

These Observatories are popular as the name Jantar Mantar.

About the Jantar Mantar

The main objective to construct these observatories in India was to get the time of day and predict the movements of the Sun, Moon, and Planet.

In the Early 18th century, Sawai Jai Singh constructed 5 Jantar Mantar, out of which the largest one in his Capital city of Jaipur is a UNESCO World Heritage Site and has the world’s largest sundial.

Out of these five astronomy marvels or Jantar Mantar of India, currently, four are operational.The one in Mathura specifically was destroyed during the 1857 war of Independence that took place between India and Britain lately.
