New Delhi - Jantar Mantar

Jantar Mantar near Connaught Place is one of the five astronomical observatories constructed by Maharajah Jai Singh I in 1725.

An enormous sundial known as the 'Prince of Dials' dominates this large-scale structure. The Jantar Mantar in Delhi is an astronomical observatory where the movements of the sun, moon and planets could be observed. Several other instruments on display were used to track the course of heavenly bodies and predict eclipses.
