The Indus Valley civilisation, at its peak, covered an area of around 480,000 km² (185,000 sq mi), an area just over half the size of present-day Pakistan. Its heartland lay in the Indus River in Pakistan, but settlements spread as far as the Makran coast, Balochistan, Afghanistan, eastern Punjab, Kutch and Saurashtra. They included cities like Harappa, Mohenjo-daro, Kalibangan, Dholavira, ports like Lothal, Sutkagen-dor and Sokhta Koh and numerous villages as well. They used irrigation to farm and constructed cities. The two main cities had sewage systems, bronze, trade tokens (early coins), and hieroglyphs. There were even baths at one of the villages, besides the great baths of brick in each city.
