Mohenjo-daro, Pakistan

One of the world's first cities — the Indus Valley Civilisation's great urban experiment, 4,500 years silent

Mohenjo-daro ('Mound of the Dead' in Sindhi) sits on the right bank of the Indus River in Larkana District, Sindh Province. Built around 2600 BCE and abandoned by 1900 BCE, it was one of the largest cities of the ancient Indus Valley Civilisation — a planned urban settlement of 40,000+ people with standardised brick sizes, straight streets on a grid, a sophisticated drainage and sewer system more advanced than contemporary Mesopotamia, and public architecture including the Great Bath.

Mohenjo-daro was established around 2600 BCE at the peak of the Indus Valley Civilisation, which at its height extended across 1.25 million km² — larger than ancient Egypt and Mesopotamia combined.
