45 Ancient Ruins That Are Even More Stunning Than the Pyramids

43. Mohenjo-Daro (Sindh, Pakistan): Indus Valley's Lost City of Planning

Lost for over 3,700 years until its rediscovery in the 1920s, Mohenjo-Daro was one of the largest and most advanced cities of the ancient Indus Valley Civilization, thriving around 2500-1900 BCE. This UNESCO site reveals unparalleled urban planning: a grid layout, sophisticated drainage and sewage systems, and impressive public baths ("The Great Bath"). The lack of grand palaces or elaborate tombs suggests a surprisingly egalitarian society. Its undeciphered script and mysterious decline add to the profound enigma of this remarkably forward-thinking ancient metropolis.
