4Mohenjo-daro – Pakistan
Mohenjo-daro, located in present-day Pakistan, was one of the major urban centers of the Indus Valley Civilization, which flourished around 2500 BCE. The city was incredibly advanced for its time, with a well-organized grid layout, sophisticated drainage systems, and impressive public baths. The reasons for its decline and abandonment around 1900 BCE remain a mystery, but theories include climate change and invasions. Rediscovered in the 1920s, Mohenjo-daro is considered one of the earliest examples of urban planning in the ancient world.
