Discuss the salient features of the Harappan architecture.
Approach · directive: “discuss”
What it asks · Describe the distinctive planning and building features of Harappan settlements — layout, materials, public and domestic structures, water systems — and what they reveal about the society.
Open with · UNESCO calls Mohenjo-daro the most ancient planned city on the Indian subcontinent, its streets meeting at right angles with drainage built into the plan; Harappan architecture is best read through that planning.
Cover
- Citadel on mud-brick platforms, walled; residential Lower Town; streets crossing at right angles
- Dholavira: fortified castle, middle town and lower town, with multi-layered fortifications
- Bricks of one 4:2:1 ratio at every settlement; extensive stone at Dholavira
- Every house linked to covered street drains; about 700 wells at Mohenjodaro; Dholavira's reservoirs
- Great Bath made watertight with bricks on edge and gypsum mortar; warehouse; Lothal dockyard of burnt bricks
- Courtyard houses; no clear palaces or temples, so authority shows through civic order
Close with · Harappan builders treated drainage and water storage as public duties; Dholavira's reservoirs, on the World Heritage List since 2021, still teach water harvesting in arid Kutch.

UNESCO calls Mohenjo-daro the most ancient planned city on the Indian subcontinent, with right-angled streets and built-in sanitation. Harappan architecture shows this planning throughout.
Planned layout
- Citadel and Lower Town: the walled Citadel rose on mud-brick platforms; the Lower Town held the homes.
- Grid of streets: roads crossing at right angles, laid out before building began.
- Dholavira's variant: a fortified castle, middle town and lower town, with multi-layered fortifications.
Standardised materials
- Uniform bricks: sun-dried or baked, length and breadth four and two times the height, at every Harappan settlement.
- Stone where suited: Dholavira, on arid Khadir island in Gujarat, used stone extensively as building material.
Drainage and water
- Covered drains: every house joined the street drains; the excavator Mackay called it "the most complete ancient system as yet discovered".
- Wells and reservoirs: Mohenjodaro had about 700 wells; Dholavira's reservoirs stored scarce water from two seasonal streams.
Public and domestic buildings
| Structure | Site | Feature |
|---|---|---|
| Great Bath | Mohenjodaro | Bricks on edge, gypsum mortar |
| Warehouse | Mohenjodaro | Massive brick base |
| Dockyard | Lothal | Burnt bricks throughout |
| Courtyard house | Lower Town | Rooms around a court |
- Restraint: no clear palaces or temples; authority shows through uniform civic order rather than display.
Harappan builders treated drainage and water storage as public duties; Dholavira's reservoirs, on the World Heritage List since 2021, still teach water harvesting in arid Kutch.
