Jantar Mantar is one of India’s most important astronomical centers. This monument, located in historic Jaipur, Rajasthan, was created to track the movement of the stars, planets and other astronomical forms in the night sky. The Hindu religion deifies the natural world and heavenly bodies, so understanding celestial movements was highly important in medieval India. Today, the monument is truly remarkable for the incredibly precise measurements and predictions made possible by the combination of shadows and interactions between these strange creations. Stone arches, scoops and staircases can all be explored, making for a surreal experience.
