Jantar Mantar in Jaipur is an open-air collection of 19 astronomical instruments built by Maharaja Jai Singh II in the 1730s. These massive stone structures were used to measure time, track celestial bodies, and predict eclipses. The sundials, including the world's largest stone sundial, are remarkably accurate. Visitors can walk among the instruments and learn about ancient Indian astronomy. The site's geometric precision and scale make it a fascinating stop for science and history enthusiasts.
