One unique aspect of the Harappan civilization in the ancient world was its city design. The cities of the Harappan civilization, also known as the Indus Valley Civilization, were remarkably well-planned. They had a grid-like pattern with streets and lanes intersecting each other at right angles. The houses were built of uniform, standardized bricks. The cities also had an advanced drainage system, with covered drains running along the streets, showing a high level of sophistication in urban planning and sanitation. This level of urban planning and standardization was unique and unprecedented in the ancient world.
