There is an image that has stayed with me since I first started looking seriously at Mohenjo-daro. Millions of fired bricks — archaeologists sometimes speak of a million for the major structures alone — and within all that colossal construction, not a single palace. Not a dominant temple. Not one statue of a king, not one bas-relief celebrating a military victory.
For a mature civilisation that existed at roughly the same time as pharaonic Egypt and the ziggurat-building cultures of Mesopotamia, this is genuinely astonishing.
A city discovered almost by accident
The story begins in 1910, when the British were building a railway line in what is now Pakistan. They needed ballast. Local people were helping themselves to bricks from a nearby hill. The British looked more closely — and discovered an ancient city buried by time.
Ten years later, John Faithfull Fleet uncovered Mohenjo-daro, another site of the same civilisation. The same architecture, the same weights and measures: he understood that these were not independent city-states but a unified civilisation. Since both cities stood on the Indus, it became known as the Indus Civilisation. It is Harappa, the first city discovered, that would eventually give it its common name.
Excavations at Mohenjo-daro began in earnest in 1927 under John Marshall’s direction. Mortimer Wheeler later introduced his “square excavation” method here, which became a standard across the field.
A million fired bricks
What strikes you immediately is the material. Mohenjo-daro is built of fired bricks — not rammed earth, not wood, not stone. Standardised, mass-produced bricks, to the same dimensions across the entire civilisation zone. From around 2800 BCE onwards, the Mature phase adopted new brick proportions — the 1x2x4 ratio — ensuring maximum structural solidity.
The city itself was erected on a brick platform, surrounded by brick walls. These walls were not there to defend against enemies — they were there to resist flooding. Every summer, during the monsoon, when the plain was flooded, it was necessary to take a boat between the lower city and the upper city. The builders of Mohenjo-daro designed their city with that parameter in mind, not against it.
What the city does not contain
It is the list of absences that speaks most loudly. No palaces. No imposing temples. No visible army, no slaves, no ostentatious wealth, no apparent poverty, no flagrant inequalities. No statues glorifying a ruler. No pyramids, no ziggurats, no monuments to the ego.
To my mind, this is the most extraordinary information archaeology has handed us about this civilisation. Not what it built, but what it chose not to build. As if, collectively, a society had decided that stone would not be used to glorify the few.
The Manhattan of prehistory
What archaeologists found instead was urban planning of remarkable precision. The cities were built in an orderly manner, with avenues running north-south and streets running east-west. Mohenjo-daro has been nicknamed “the Manhattan of prehistory” — which, for once, is not rhetorical excess.
The city was divided into two or three distinct parts: the lower city, the upper city, and what nineteenth-century archaeologists called “the citadel” — a term borrowed from their knowledge of Greek and Roman civilisations that does not quite match what they found. It was a raised section, surrounded by walls, housing large open common rooms — places of gathering, not command.
Flush toilets for everyone
Here is the detail that, more than any other, tells me something about this civilisation’s philosophy. Even the most modest houses were equipped with a bathroom and a sewage system. Dry toilets in every house. A few flush toilets, which existed nowhere else at the time. And, it seems, public toilets.
Water is the absolute priority. Wells at every crossroads — some reaching thirty metres deep, lined with trapezoidal bricks for exceptional solidity. Wastewater was drained outside the city limits. And at the heart of the “citadel” area, a great bath in the shape of a pool, built for ablutions, with small rooms around it and steps leading down into the water.
This great bath was probably used for purification rituals. Archaeologists who have found seals depicting yoga postures at Mohenjo-daro — identical to postures still practised today — may have a partial answer there about the nature of those rituals.
A decentralised civilisation
What makes Mohenjo-daro even more remarkable is that it was not a capital. It was one city in a decentralised network of autonomous, interconnected urban centres. At the civilisation’s peak, around 1900 BCE, there were approximately a thousand cities across this territory.
No central palace, no single visible authority. Local councils or assemblies, the archaeologists suggest. A social structure that was neither centralised nor authoritarian — unique among the great civilisations of antiquity, and perhaps of any era.
What a million bricks say
I keep returning to that opening image: millions of bricks, no palace. This architectural choice is a social choice. Mohenjo-daro says something fundamental about what a civilisation can decide to value. Not the glory of a sovereign, not the power of an institutional god — the comfort of every inhabitant, access to water for all, open shared spaces.
This may be the most difficult lesson for our contemporary societies: this civilisation functioned, and functioned well, for several centuries, without any of the markers we habitually associate with “power.”
