Harappan Period (town planning, Great Bath, granaries)
Art & Culture › Architecture · Topic 1.1
Harappan architecture, also called Indus Valley Civilisation architecture, dates to the mature phase of c. 2600 to 1900 BCE and is the earliest urban building tradition of the subcontinent. Cities were planned on a grid with standard burnt brick, covered drains and a raised citadel above a lower town. The best-known structures are the Great Bath and granary at Mohenjodaro (Mohenjo-daro, Sindh, Pakistan), the granaries of Harappa (Punjab, Pakistan), the Lothal dockyard and the Dholavira reservoirs (both Gujarat; Dholavira is a World Heritage Site since 2021). Harappa was found by Daya Ram Sahni in 1921 and Mohenjodaro by R. D. Banerji in 1922. No temple has been firmly identified.

Where Does It Fit?
This is the first topic of the macro on architecture and the starting point of the story of Indian building traditions. Later topics move from the Mauryan stone tradition to temple styles. The Harappan phase matters because it shows a planned urban culture without any known monumental temple. Next topic: Mauryan Architecture (Ashokan pillars, palaces).
What Were the Main Features of Harappan Town Planning?
| Feature | Details |
|---|---|
| Grid pattern | Streets cut each other at right angles, dividing the city into rectangular blocks. Main streets ran north-south and east-west |
| Two-part city | A raised citadel in the west for public and ritual buildings and a larger lower town in the east for houses. Dholavira had three parts, a citadel, a middle town and a lower town |
| Burnt brick | Standard bricks in the ratio of about 4:2:1 (length, width, thickness) were used across all sites, showing a common standard |
| Drainage | Houses had bathrooms and soak pits. Wastewater went to covered street drains of brick with manholes for cleaning |
| Houses | Flat-roofed, one or two storeys, built around a central courtyard, with no windows facing the main street. Many had private wells |
| Fortification | Citadels and in places the lower towns were walled. Kalibangan, Dholavira and Surkotada show fortified settlements |
| Lack of temples | No large temple or palace has been proved. Large public buildings were used for storage, bathing or assembly |
Which Structures and Sites Are Most Asked About?
| Structure or site | State or country | Period | Key fact |
|---|---|---|---|
| Great Bath, Mohenjodaro | Sindh, Pakistan | Mature phase, c. 2600 to 1900 BCE | A large brick tank about 12 m by 7 m and over 2 m deep, with steps on two sides and a bitumen layer for waterproofing. Probably used for ritual bathing |
| Granary, Mohenjodaro | Sindh, Pakistan | Mature phase, c. 2600 to 1900 BCE | The largest building at the site, on the citadel, raised on a brick platform with air channels |
| Granaries, Harappa | Punjab, Pakistan | Mature phase, c. 2600 to 1900 BCE | Two rows of six granaries near the river with working floors for pounding grain |
| Lothal dockyard | Gujarat, India | Mature phase, c. 2400 BCE onward | A brick basin usually described as a tidal dock for ships. Excavated by S. R. Rao |
| Dholavira | Gujarat, India | Early to mature phase, c. 2650 to 1900 BCE | Stone-built city on Khadir island with a series of water reservoirs and a large inscription of ten signs. Excavated by R. S. Bisht. World Heritage Site 2021 |
| Kalibangan | Rajasthan, India | Early to mature phase, c. 3rd millennium BCE | A ploughed field and fire altars in houses and on the citadel. Excavated by B. B. Lal and B. K. Thapar |
| Rakhigarhi | Haryana, India | Early to mature phase, c. 3rd millennium BCE | Among the largest Harappan sites, in Hisar district |
| Chanhudaro | Sindh, Pakistan | Mature phase, c. 2600 to 1900 BCE | A craft town with no citadel |
| Surkotada | Gujarat, India | Late mature phase, c. 2000 BCE | A fortified site where horse bones have been reported |
What Else Should You Remember?
- Discovery: Daya Ram Sahni found Harappa in 1921 and R. D. Banerji found Mohenjodaro in 1922, under John Marshall as Director General of the Archaeological Survey of India
- Great Bath features: The bath sat in a courtyard with rooms and a well nearby, and a drain led from one corner. Its brickwork used gypsum mortar for tight joints
- Granary debate: Some scholars call the large Mohenjodaro building a granary and others a public hall, so the safe wording is that it is traditionally called a granary
- Ritual structures: Fire altars at Kalibangan and Lothal point to ritual use of fire, but no temple has been identified with certainty
- Water management: Dholavira built dams, channels and rock-cut reservoirs to store seasonal rain, one of the finest water systems of the ancient world
- Dholavira signboard: A gateway carried a large signboard with ten big letters of the Harappan script, still undeciphered
- Material by region: Sites in Gujarat such as Dholavira used dressed stone, while most Indus plain sites used brick
- Lothal features: A warehouse, a bead-making workshop and the dock show the importance of maritime trade with Mesopotamia
- Mohenjodaro World Heritage: The Archaeological Ruins at Moenjodaro in Pakistan were inscribed in 1980. The Indian site Dholavira was inscribed in 2021 as Dholavira: A Harappan City
- Scientific study: Town planning and engineering are also studied in Town Planning and Engineering (Harappan Drainage Systems), and art in Sculptures of Harappan Civilisation
- Alternate names: The civilisation is called Harappan, Indus Valley or Indus, and Mohenjodaro is spelt Mohenjo-daro or Moenjodaro in UNESCO records. The Great Bath is also called the Great Bath of Mohenjo-daro
- Burial: Cemetery R-37 at Harappa and the cemetery at Lothal show burial practice, but monumental tombs are absent
Why Does It Matter for the Exam?
- Site matching: questions ask for the site with the Great Bath, dock, fire altars or reservoirs
- State of the site: Dholavira and Lothal in Gujarat, Kalibangan in Rajasthan, Rakhigarhi in Haryana
- Planning features: grid pattern, covered drains, burnt brick and the two-part city
- Statements: typical traps are that Harappans built temples or used lime mortar for all walls
- Excavators: Sahni, Banerji, S. R. Rao, R. S. Bisht, B. B. Lal
As an analytical point, Harappan planning shows that civic engineering, standard weights and bricks, and shared water systems existed before any large empire. The lessons for modern urban planning, such as drainage first and zoning of activities, are a useful way to connect the past to present cities.

Frequently Asked Questions
What was special about Harappan town planning?
Harappan cities were laid out on a grid pattern with straight streets crossing at right angles. Each had a raised citadel and a lower town, standard burnt bricks, houses around courtyards and covered drains with manholes. This level of planning was not seen in other contemporary cultures of India.
What is the Great Bath of Mohenjodaro?
The Great Bath is a large rectangular brick tank on the citadel of Mohenjodaro in Sindh, about 12 m long, 7 m wide and over 2 m deep. It has steps on two sides, a waterproof bitumen layer and an outlet drain, and was probably used for ritual bathing.
Which Harappan site has a dockyard?
Lothal in Gujarat has a brick structure widely regarded as a tidal dockyard. It was excavated by S. R. Rao and is linked with maritime trade with Mesopotamia. Lothal also had a warehouse and a bead-making workshop, which supports the view that it was a trading town.
Why is Dholavira important?
Dholavira in Kutch, Gujarat, was built partly in stone and had three divisions, an advanced system of reservoirs and channels, and a large signboard with ten signs of the Harappan script. It was inscribed as a UNESCO World Heritage Site in 2021, the first Harappan site in India to be listed.
Did Harappans build temples?
No temple has been clearly identified at any Harappan site. Large buildings such as the Great Bath and the granaries served civic purposes, though fire altars at Kalibangan and Lothal suggest ritual practice. Scholars therefore describe Harappan religion mainly from seals, figurines and altars instead of temples.
What are the other names of the Harappan Civilisation?
The Harappan Civilisation is also called the Indus Valley Civilisation or the Indus Civilisation. It is named after Harappa, the first site found, in 1921. Mohenjodaro is also spelt Mohenjo-daro. Its mature phase, c. 2600 to 1900 BCE, spread over Pakistan and the Indian states of Gujarat, Rajasthan, Haryana and Punjab.
What is the difference between the citadel and the lower town in Harappan cities?
The citadel was a raised, often walled western mound holding public and ritual structures such as the Great Bath and granaries. The lower town lay to the east at ground level and held houses, workshops and streets. Dholavira differs, having a citadel, a middle town and a lower town.
What is the difference between Harappa and Mohenjodaro?
Harappa lies in Punjab, Pakistan, near the old course of the Ravi, and was found by Daya Ram Sahni in 1921. Mohenjodaro lies in Sindh, Pakistan, on the Indus, and was found by R. D. Banerji in 1922. Mohenjodaro has the Great Bath, while Harappa has the granaries and Cemetery R-37.
Why is Harappan architecture important for UPSC?
Prelims asks for the site with the Great Bath, dock, fire altars or reservoirs, the state of each site and its excavator. Mains uses Harappan planning to discuss ancient urbanism, drainage and water management. Dholavira, a World Heritage Site since 2021, gives a current affairs link as well.
