What was Harappan town-planning like?

Harappan town planning was highly advanced and organized. The cities were laid out in a grid pattern, with streets running perpendicular to each other. The buildings were made of baked brick, and many houses had private wells and bathrooms. A sophisticated drainage system was in place, with drains running along the streets, demonstrating the Harappans’ concern for cleanliness. The cities also had large public baths, such as the Great Bath in Mohenjo-daro, indicating their focus on communal spaces and hygiene. This planning reflects the Harappans’ remarkable engineering and urban management skills.
