UPSC CSE Mains 2025 GS1 - Q1 Discuss the salient features of the Harappan architecture.

Q. Discuss the salient features of the Harappan architecture.

Possible Introductions

Civilisational framing

The Harappan or Indus Valley Civilization (2600–1900 BCE), one of the world’s earliest urban cultures, displayed a remarkable architectural tradition that combined functionality, aesthetics, and civic planning, reflecting a sophisticated socio-political order.

Archaeological evidence based

Excavations at Harappa, Mohenjo-Daro, Dholavira, and Kalibangan reveal that Harappan architecture was defined by standardized layouts, advanced construction techniques, and civic engineering unparalleled in the ancient world.

Comparative framing

While contemporary civilizations like Mesopotamia and Egypt focused on monumental architecture, Harappans innovated in urban planning and functional civic architecture, underlining a unique approach to built space.

Micro-narrative intro (current link)

The 2021 UNESCO recognition of Dholavira as a World Heritage Site has revived attention towards Harappan architecture, which demonstrates timeless lessons in sustainable water management and urban design.

Directive Analysis

“Discuss” → requires a multi-dimensional exploration of Harappan architecture: its salient features, types (domestic, civic, monumental, religious), and significance. The answer must avoid mere listing, instead show integration of function, form, and societal values.

Main Body

Salient Features of the Harappan Architecture

1. Urban Planning and Layout

    • Grid pattern towns with streets intersecting at right angles (Harappa, Mohenjo-Daro).

    • Segregation into citadel (public structures) and lower town (residential areas).

    • Evidence of zoning for trade, habitation, and religious purposes.

X-Factor: Sir John Marshall called it the “first urban revolution in South Asia.”

2. Building Materials and Techniques

    • Standardized baked bricks (ratio 1:2:4) and sun-dried bricks for different purposes.

    • Use of gypsum mortar and wooden beams in some sites.

    • Stones used in Dholavira due to local availability.

X-Factor: Brick uniformity suggests centralised authority or shared cultural ethos.

3. Domestic Architecture

    • Houses with courtyards, private wells, bathrooms, and covered drains.

    • Multi-roomed structures with upper floors and staircases.

    • Uniform housing patterns indicated egalitarian tendencies.

    • Example: At Mohenjo-Daro, about 700 wells have been discovered—indicating individual access to water.

4. Civic and Public Architecture

    • Great Bath (Mohenjo-Daro): earliest water tank, possibly for ritual purification.

    • Granaries (Harappa, Mohenjo-Daro, Lothal): brick platforms for surplus storage.

    • Dockyard (Lothal): advanced hydraulic engineering, linked to maritime trade.

X-Factor: Great Bath called the “earliest public water tank in human history” by historians.

5. Water Management & Drainage Systems

    • Covered drains with inspection traps.

    • Sophisticated rainwater harvesting and reservoirs (Dholavira).

    • Wells within houses and public tanks.

X-Factor: Dholavira had a unique system of reservoirs—early evidence of sustainable water architecture in arid zones.

6. Religious and Monumental Structures

    • No grand temples or palaces found → focus on civic architecture over ritual monuments.

    • Fire altars at Kalibangan; possible cult structures at Harappa.

    • Interpretation: a civic-secular ethos unlike Mesopotamia’s ziggurats or Egypt’s pyramids.

7. Specialized Architectural Features

    • Fortifications: defensive walls of mud-brick/stone (Dholavira).

    • Standardized weights and measures inscribed on platforms and workshops.

    • Marketplaces and workshops show integration of trade with urban planning.

Sweet Spot / Diagram Suggestion

    • Flowchart: Harappan architecture → (Urban planning → Domestic → Civic → Drainage → Special features).

    • Map of IVC sites showing regional variations (stone in Gujarat, bricks in Punjab).

Possible Conclusions

Civilisational legacy-based

Harappan architecture, rooted in functionality and civic sense rather than monumentality, laid the foundations of South Asia’s urban traditions.

Contemporary learning

From drainage in Mohenjo-Daro to water harvesting in Dholavira, Harappan architecture provides timeless models for sustainable urbanism in today’s climate-stressed world.

Philosophical

Unlike contemporary civilizations that glorified rulers, Harappan architecture glorified the community itself—its collective civic life and egalitarian ethos.

Report-based

As UNESCO (2021) stressed while recognized Dholavira to be one of the very few historical sites from the ancient times to be preserved in South Asia and highlighted its universal outstanding value.
