How bricks were arranged to build walls in harappan cities?

The Harappan cities, like Mohenjo-daro and Harappa, used standardized baked bricks for construction. Walls were often arranged in modular patterns, with bricks laid in horizontal rows and overlapping joints for stability.

They followed a grid layout, and the brick sizes were uniform, which shows advanced urban planning. This method ensured strength and durability in their structures.
