The distinctive features of urban centres in Harappan civilization are.

1. The division of town into Citadel and lower town where, citadel was on the higher ground with its huge structure probably used for public purposes and the lower town wheere we find the residential area with its distinct architecture.

2. Drainage system- It was one of the most important feature of the urban centres, it was neatly laid with idea to keep it clean and was connected with every drain of the residential area.

3. streets- Every part of the town was connected with roads and street. It was laid out along an approximate “grid” pattern, intersecting at right angles. It appears that drain and streets were laid out first and then houses were built along them.
