For 900 years, Moenjodaro, a city in what is now Pakistan, was the urban hub of a thriving civilization, the New York or London of its day. Around 1700 B.C., residents suddenly abandoned the Indus Valley city, and it was lost in the sands of time until archaeologists began excavating it in the 1920s.Today, visitors can wander for hundreds of acres among its deserted streets and homes.
