Lothal, located in present-day Gujarat, was one of the major port cities of the Indus Valley Civilization. It is significant for its dockyard, which is considered one of the earliest examples of maritime infrastructure. This dockyard was connected to the Sabarmati River, facilitating trade and commerce with distant regions such as Mesopotamia. The presence of a sophisticated drainage system, bead-making workshops, and tools further underscores Lothal’s importance as a center of trade, craftsmanship, and culture in the ancient Indus Valley Civilization.
