Granaries and public buildings

1. Public architecture in the Harappan city

The Indus or Harappan Civilization developed a distinctive urban tradition across northwestern South Asia. Its Mature Harappan phase, about 2600–1900 BCE, produced planned settlements, substantial brick or stone structures, drainage networks and water-storage installations. Harappa lies in present-day Punjab, Pakistan; Mohenjo-daro is in Sindh, Pakistan. Dholavira and Lothal are important examples in Gujarat, India. Their large structures provide evidence of collective organisation, but do not by themselves establish a single political system across the civilization.

At several sites, an elevated, enclosed sector is conventionally called the citadel, while another sector is described as the lower town. These are archaeological terms, not names preserved from Harappan texts. The elevated sector could contain large buildings and water installations, but elevation does not prove that it was exclusively a military fortress or royal enclosure. Raised platforms also helped protect buildings from inundation and supported substantial construction.

Public building is best understood here as a cautious designation for structures whose scale, location or specialised features suggest functions extending beyond an ordinary household. Access may nevertheless have been restricted. Unlike Mesopotamia and Egypt, the Harappan world has yielded no securely identified monumental royal palace, temple complex or royal tomb. Since the script remains undeciphered, building functions must be reconstructed from architecture, artefacts and archaeological context.

2. Granaries: conventional labels and contested evidence

At Harappa, a complex near Mound F was traditionally identified as a granary. It comprises twelve rectangular building blocks arranged in two parallel rows of six, separated by a passage. The remains are primarily brick foundations; reconstructions often envisage timber superstructures and raised floors. Nearby circular brick platforms and associated working areas encouraged interpretations linking this locality with grain processing and storage.

The traditional explanation treated spaces between the foundations as ventilation channels that would keep stored grain dry. Circular platforms were interpreted as bases for pounding grain. Together, these features appeared to support a model in which agricultural surplus was collected and redistributed by urban authorities. This remains a familiar textbook account, but the presumed storage function is not conclusively demonstrated by the architecture alone.

At Mohenjo-daro, a massive brick-supported structure near the Great Bath was also labelled a granary. The label depended heavily on reconstructions of raised floors, ventilation passages and a presumed storage superstructure. Secure evidence demonstrating bulk grain storage in the building is lacking. NCERT therefore uses the more cautious term warehouse when discussing this major citadel structure, while archaeological scholarship continues to question specific functional identifications.

Absence of preserved grain cannot by itself disprove storage, because organic materials decay and buildings may be cleared or reused. Nevertheless, a large platform cannot establish the storage of grain, collection of taxes in kind or operation of a state redistribution system. Stronger identification would require converging evidence such as storage containers, botanical concentrations, residues, handling facilities and a consistent archaeological context.

3. The Great Bath and other buildings at Mohenjo-daro

The Great Bath is among the most securely recognisable specialised structures of the civilization. Situated in Mohenjo-daro’s citadel sector, its rectangular tank measures approximately 12 by 7 metres and is about 2.4 metres deep. Steps descend into it from the north and south. Carefully laid bricks, gypsum mortar and bitumen waterproofing helped limit leakage. A surrounding complex included corridors and rooms.

A well in an adjoining room is generally understood as a source of water, while an outlet drained the tank. These features demonstrate deliberate provision for filling, retaining and removing water. Its distinctive setting and substantial construction have led scholars to suggest ceremonial or ritual bathing. This is a plausible interpretation, not proof of a particular religion, priesthood or direct continuity with later Indian ritual practices.

Other large buildings at Mohenjo-daro have been described as an assembly hall and a college or residence of priests. A pillared hall could have accommodated gatherings, but the activity conducted there is uncertain. Likewise, a sizeable multi-roomed structure cannot establish the existence of a college or organised priestly institution. These conventional names should be distinguished from excavated features such as pillars, courtyards, rooms and entrances.

The wider city also contained numerous wells, bathing floors and covered drains. Such facilities reveal that investment in water and sanitation was not confined to a single monument. Household drains commonly connected to street drainage, often through arrangements intended to trap solids. The system implies planning and maintenance, although it does not identify the precise institution responsible.

4. Regional examples: Dholavira and Lothal

Dholavira, on Khadir island in the Great Rann of Kachchh, demonstrates that Harappan architecture was not uniformly brick-built or organised into only two sectors. Stone was used extensively, and the settlement had multiple enclosed divisions, gateways, open spaces and an elaborate water-management system. Its reservoirs and channels collected runoff and seasonal stream water in a landscape where water availability was a major constraint.

Dholavira’s large reservoirs are more securely identified by their physical characteristics than are many supposed granaries. Their excavated basins, steps and associated water channels provide direct functional evidence. Large open grounds have also been interpreted as spaces for gatherings or ceremonies, although particular activities remain uncertain. The site became a UNESCO World Heritage property in 2021.

At Lothal, excavators identified a raised warehouse platform divided into square blocks with passages between them. Sealings recovered from the associated context strengthen the interpretation of storage and handling of goods. This does not mean that the facility stored only grain. Lothal’s large brick-lined basin is conventionally described as a dockyard, but alternative interpretations exist. In examination answers, distinguish the better-supported commercial associations of the settlement from disputed claims about individual structures.

5. What these structures reveal about Harappan society

Large platforms, reservoirs and drainage systems required skilled labour, materials, measurement and coordination. Standardised construction practices, including the widespread 1:2:4 thickness-width-length ratio of Harappan bricks, suggest shared technical conventions. These features support the existence of institutions capable of organising substantial work, but do not demonstrate whether authority rested with kings, merchants, ritual specialists, councils or combinations of these groups.

Agriculture sustained Harappan urban populations, while exchange connected settlements and production zones. Storage was therefore important even if particular monumental granaries remain uncertain. Storage could have occurred in households, workshops or other buildings that have not been securely identified. For Prelims, learn the conventional site associations while attending to qualifiers such as conclusively proved. For Mains, use public architecture to discuss urban coordination and surplus management without presenting a hypothetical centralised granary system as established fact.
