Jaipur Observatory

Between 1724 and 1730 Maharajah Sawaii Jai Singh II of Jaipur constructed five astronomical observatories in north 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. It is truly amazing at the accuracy of the sun dials and alignment with the horizon to measure the azimuth.
