The examples:

 (i) The settlements is divided into two sections, one smaller but higher and other much larger but lower.

 (ii) Archaeologists designate these as the Citadel and Lower Town respectively. The citadels owes its height to the fact that buildings were constructed on mud brick platforms. It was walled, which meant that it was physically separated from the lower town.

 (iii) One of the most distinctive features of Harappan cities was the carefully planned drainage system. The roads and streets were laid out along an approximate grid pattern, intersecting at right angles.

 (iv) The lower Town at Mohenjodaro provides examples of residential buildings. Every house had its own bathroom paved with bricks, with drains connected through the wall to street drains.

 (v) Many houses had wells, often in a room that could be reached from the outside and perhaps used by passer-by. Some houses have remains of staircases to reach a second storey or the roof.
