Mohenjo-daro: reading a city plan
2600 BCE–1900 BCE (focus interval)
What can a plan tell us before we name its rulers?
Mohenjo-daro’s surviving city plan raises a practical question: how were shared spaces and infrastructure coordinated? Its ordered layout alone cannot identify rulers or tell us which language residents spoke.

What this case covers
What was found
The third-millennium BCE archaeological city preserves a structured urban layout.
What it may tell us
Drainage and the city plan can be examined without assuming a particular constitution or ruler.
Alternative explanations and limits
The plan alone cannot identify rulers, a system of government or the residents’ language.
Access and review notes
The drainage study was inspected through its abstract. Harappa.com’s account is a synthesis of earlier research, not a newly reviewed excavation report. Independent review remains open.
Read the evidence
Source links apply to specific claims. Several links can lead back to the same study. Read what each source supports.
The third-millennium BCE archaeological city preserves a structured urban layout.
What remains uncertain
The plan alone cannot identify rulers, a system of government or the residents’ language.
Method and source passage
Institutional primary description; introductory synthesis
Description and statement of Outstanding Universal Value
The authors interpret the drainage system primarily as removing wastewater from paved rooms near wells.
What remains uncertain
An abstract does not expose all calculations, assumptions or counterexamples.
Method and source passage
Engineering interpretation reported in abstract
English abstract, concluding sentence
Their analysis considers water supply, rainfall and patterns of water use alongside wells, drains and soak-pits.
What remains uncertain
These parameters do not establish a modern-style sewer system or a form of government.

Questions that remain
- What can a plan tell us before we name its rulers?
- Which independent evidence would refine or challenge this account?
Settlement
Drainage and the city plan can be examined without assuming a particular constitution or ruler.
Limit: The plan alone cannot identify rulers, a system of government or the residents’ language.
UNESCO World Heritage Centre: Mohenjo-daro ↓Water and daily space
Drains can be studied in relation to rooms and wells, rather than named as a generic sanitation system.
Limit: The proposed function remains an interpretation.

Engineering questions complement archaeological plans.
Limit: Full-paper methods and archaeological source dependence still need review.
