Which city was notable for its large scale indicative of centralized planning within the Indus Valley?

Mohenjo-Daro is recognized as one of the key cities of the Indus Valley Civilization, showcasing some of the earliest examples of urban planning and sophisticated city layout that is characteristic of centralized planning. The city was meticulously planned with a grid pattern of streets, advanced drainage systems, and standardized fired-brick buildings, indicating a highly organized and structured approach to urban development.

The existence of large public buildings, such as the Great Bath and a centralized granary, suggests a significant level of communal administration and social organization. These features point to the ability of the society to coordinate large-scale construction projects and maintain public works, which is a hallmark of centralized governance.

In contrast, the other cities listed, such as Harappa, Thebes, and Memphis, do demonstrate early urban planning as well, but Mohenjo-Daro stands out within the context of the Indus Valley for its uniformity and advanced engineering, reflecting a particularly high degree of sophistication in urban planning and governance that is emblematic of this ancient civilization.
