Grinding grain in the Indus ValleyThe Indian civilization is one of the oldest in the world. Farmers had begun to build villages in the valley of the River Indus by about 7000 BC. These settlements grew larger and eventually became the centre of a great civilization that flourished from about 3200 BC until about 1700 BC. The largest cities of that civilization have been named Mohenjo-Daro and Harappa by archaeologists. The inhabitants constructed great buildings and made beautiful crafts.
Indus valley civilization
A model showing everyday life in an Indus Valley city, c. 2600 BCHarappa and Mohenjo-Daro had streets of brick-built houses laid out on a grid system. Their thick walls kept people cool in the heat of summer, while the windows may have had wooden shutters with grilles (barred openings) to let in light and air.
From 2600 BC, cities of the Indus Valley featured basic "flush" toilets in nearly every house, connected to common sewer pipes.
