A visit to the Jantar Mantar astrological/astronomical observatory in Jaipur is a must.
Between 1724 and 1730 Maharajah Sawaii Jai Singh II of Jaipur constructed five astronomical observatories in northern India. The observatories, or “Jantar Mantars” as they are commonly known, incorporate multiple buildings of unique form, each with a specialized function for astronomical measurement. These structures, with their striking combinations of geometric forms have captured the attention of architects, artists, and art historians world-wide. Your time will not be wasted.
