The Harappan Civilization, also known as the Indus Valley Civilization, is best known for its highly developed urban centres. These cities, such as Harappa, Mohenjo-Daro, and Lothal, were characterized by sophisticated urban planning, well-constructed buildings, drainage systems, and a high level of organization. The Harappans are credited with creating one of the earliest known urban societies, with planned streets and standardized brick construction.
The development of these urban centres was unique for its time, reflecting the advanced engineering and organizational skills of the Harappan people.
