In a groundbreaking excavation at the Rakhigarhi archaeological site in Haryana, researchers have unearthed a rare copper plate featuring what appears to be a standardized urban map of a Harappan neighborhood. This discovery provides the first physical evidence that Indus Valley planners utilized etched blueprints to maintain the remarkable geometric precision of their cities.
The plate, found in a newly designated residential sector, shows a grid of parallel streets and a sophisticated drainage network that aligns perfectly with the excavated ruins. Archaeologists believe this finding confirms the existence of an administrative municipal body responsible for urban design over 4,000 years ago.
