Explain in detail the city planning …

The people of the Indus Valley civilisation provided explicit attention to elaborate town planning:

1. The streets cut each other at right angles.
2. The main streets were over 800 metres long and 10 metres wide. They were also curved at the corners in order to make it easy for bullock carts to pass. The streets were generally paved with baked bricks.
3. Houses were built on both the sides of the street.
4. The city was generally divided into two parts - lower and upper (citadel or acropolis).
5. The upper part was built on a raised platform which protected people during floods. It consisted of buildings such as the Great Bath, Town Hall, the Great Granary and some temple-like structures.
6. The lower part was at a lower height but bigger in area. It had small buildings and houses of the common people.
