Moenjodaro rises from the flat plains of upper Sindh as a field of low brick walls, wide streets and neat house plans. It is one of the great cities of the Indus Valley Civilization, and walking its lanes gives a rare look at urban life from more than four thousand years ago.
The city flourished around 2500 BCE and was one of the largest settlements of its time. It is known for its grid layout, covered drains, wells and brick houses, along with the Great Bath, which suggests careful civic planning. The site was abandoned around 1900 BCE, and the reasons are still debated. It was rediscovered in the 1920s and inscribed as a UNESCO World Heritage Site in 1980. Salty groundwater, flooding and weathering threaten the brickwork, and conservation work is ongoing.
