A Possible Harappan Astronomical Observatory at Dholavira

Research suggests that Dholavira, a significant Harappan port city located on the Rann of Kutch, may have housed an astronomical observatory. The study focuses on two circular rooms within the site's structures, proposing that strategically placed holes in their ceilings could have facilitated the internal movement of sunlight, indicating advanced astronomical knowledge. By analyzing these architectural features, the authors argue that such dedicated structures likely existed across major Harappan cities, reflecting a sophisticated understanding of astronomy during this ancient civilization.
